KEMORELA 2PCS 20oz Double Wall Glass Tumblers review

Have you ever wanted a stylish, practical cup that keeps my matcha cold without leaving a puddle on the table?

First Impressions

When I first saw the KEMORELA 2PCS 20oz Double Wall Glass Tumblers with Lids and Straws – Insulated Borosilicate Glass Matcha Cups for Iced Matcha Latte, Smoothies, Reusable Travel Glass Cups – Leak Proof 2-in-1 Lid, I was struck by how modern and clean the design looked. The set comes with two identical tumblers that feel thoughtfully designed for everyday use and for anyone who appreciates glassware that looks as good on the kitchen counter as it does in a work meeting.

Packaging and Presentation

The tumblers arrived well-packaged and individually wrapped to reduce the risk of breakage during shipping. I appreciated the minimal, protective packaging that balanced safety and sustainability, and I felt like the unboxing reflected the product’s blend of function and style. There was nothing over-the-top; everything inside was exactly what I needed to start using the cups immediately.

Unboxing Experience

Opening the box, I found two tumblers, two lids, and two reusable straws arranged neatly, each piece protected with foam and plastic film in key areas. The inclusion of two complete sets makes this ideal for sharing or keeping one at home and one in my bag. It’s a small detail, but having both straws and lids included means no extra shopping before my first iced matcha.

Design and Build Quality

The design is where these tumblers stand out for me. They feel modern and intentional, with a clear emphasis on both aesthetics and day-to-day practicality. The double wall borosilicate glass not only looks elegant but also gives a premium feel when I hold the cup.

Glass Material: Borosilicate Benefits

Borosilicate glass offers several benefits compared to typical soda-lime glass. I like that it’s more resistant to thermal shock, which means I can move between hot and cold beverages with more confidence. It’s also typically lighter and clearer, and this set feels robust despite the delicate appearance.

Double Wall Insulation and No Condensation

The double wall design is one of my favorite features because it effectively prevents condensation. When I pour iced matcha or a blended smoothie, the outer surface stays dry, so I don’t have to worry about rings on my desk or a soggy coaster. The insulating air gap also helps with temperature retention without isolating the aroma and flavor of the drink.

Lids and Straws: 2-in-1 Leak Proof Lid

Each tumbler includes a 2-in-1 lid that I can use either for direct sipping or with the included straw. The silicone ring inside the lid provides a secure seal and reduces spills, even when the tumbler is inverted briefly. I found the lid design both clever and convenient for switching between straw use and a traditional sip opening.

Performance

I tested the tumblers both at home and on the go, using hot tea, iced matcha lattes, smoothies, and plain water. They performed reliably across scenarios and made everyday beverage routines more pleasant.

Temperature Retention: Hot Drinks

When I used the tumblers for hot beverages like tea, they kept the liquid warmer for longer than a single-walled glass. The double wall provides a barrier to heat transfer so the cup doesn’t feel scalding to the touch. While it’s not a thermos level of insulation, the tumblers strike a nice balance for sipping hot tea or coffee leisurely.

Temperature Retention: Cold Drinks and Iced Matcha

For iced matcha lattes and other cold drinks, the tumblers excel. The insulation slows warming and prevents external condensation, which lets me enjoy the cold drink longer without constantly wiping the cup. If I’m making iced matcha at home and want to sip slowly over an hour, the drink stays refreshing and cold.

Spill Resistance and Leak Proof Testing

The 2-in-1 lid seals well thanks to the silicone ring, and it performs as advertised when right-side up and when placed on my bag. I tested the lid inverted briefly and didn’t encounter leaks; however, I still avoid putting the tumbler completely upside down in a backpack as a precaution. The lid is reliable for normal travel and commuting use, and it reduces accidental spills in a café or office setting.

Dishwasher and Everyday Use

The tumblers are advertised as dishwasher safe, and I ran them through a standard dishwasher cycle without issues. I also washed one by hand with warm soapy water and a bottle brush; the double wall and rim cleaned up easily. The reusable aspect and durability make these cups practical for daily use, and I appreciated the reduced need for single-use cups.

Comfort and Usability

Comfort in daily use played a big role in my experience. I wanted something that was comfortable to hold, easy to drink from, and uncomplicated to clean. These tumblers meet those expectations in several ways.

Grip, Weight, and Drinking Experience

When filled, the tumblers feel balanced in my hand—neither too heavy nor too light. The double wall keeps the exterior comfortable to hold even with hot contents inside. The wide mouth makes sipping and cleaning straightforward, and the clear glass lets me see the beverage level easily.

Straw vs Sip Hole Usage

The 2-in-1 lid gives me flexibility: I can sip directly from the lid opening when I want a hot drink or use the straw for cold beverages. The included reusable straw is convenient for smoothies and iced matcha, and swapping between straw and direct sipping is quick and intuitive. I like being able to choose based on the drink and my surroundings—sipping directly in a quiet setting, or using the straw while walking.

Cleaning and Maintenance

Cleaning is simple. The tumbler bodies are dishwasher safe, and the lids and straws cleaned well in the dishwasher too, although I sometimes hand wash the silicone ring to make sure no residue gets trapped. The wide mouth helps a brush reach the inside easily, and I haven’t noticed any lingering odors or stains after regular use.

Sustainability and Practicality

Using reusable glass tumblers reduces single-use waste, and the KEMORELA set feels designed with sustainability in mind. The durable borosilicate glass and reusable lids/straaws make this a greener choice than disposable cups and plastic tumblers.

Environmental Impact Compared to Disposable Cups

Switching from single-use plastic or paper cups to these reusable glass tumblers cuts down on waste for me considerably. Because they’re reusable, dishwasher-safe, and built from durable materials, they reduce the frequency of replacing cups and lower the long-term environmental impact.

Durability & Longevity

The borosilicate construction gives me confidence in the longevity of these tumblers. I treat them as daily-use items and expect them to last for a long time with reasonable care. The fact that there are two tumblers in the set also helps: I can keep one as a spare if the other is in the dishwasher or if I want to take one on a trip.

Value and Use Cases

I evaluated the product value based on materials, functionality, and how often I’d actually use them. The set delivers high utility for a reasonable price given the materials and features.

Who Should Buy These Tumblers?

These tumblers suit anyone who drinks matcha, iced coffee, smoothies, or hot tea and wants a reusable, attractive, and practical cup. They’re excellent for people who work from home, go to an office, or exercise and want a leak-resistant travel option. If you care about aesthetics and environmental impact, this set is a solid choice.

Where I Use Them

I use one tumbler for morning iced matcha while working at my desk and the other for afternoon iced coffee or a smoothie. They’re also my go-to when I’m heading to a café with a reusable cup policy or taking drinks on a short commute. The tumblers are versatile enough for both home and travel use.

Pros and Cons

I always weigh pros and cons to help decide a purchase. Below I list what I found especially helpful and what could be improved.

Pros

• Excellent double wall insulation that prevents condensation.

• I’m cautious about tossing it completely upside down in a bag despite the leak-proof claim.
• The product details don’t specify the straw material and some users may prefer glass or stainless straws for long-term durability.
• Glass, while durable, is still breakable if dropped—needs careful handling compared to metal tumblers.

How I Use the Cups—Practical Examples

I prefer practical examples to understand how a product fits into my life. Below I share concrete ways I use the tumblers and how they perform in each scenario.

Morning Iced Matcha Routine

In the morning, I make an iced matcha latte, fill one tumbler with ice and the drink, and use the straw. The tumbler keeps the matcha cold and the outer glass stays dry, so I don’t have to worry about condensation on my desk. The clear glass also makes the drink look inviting; I enjoy the visual aspect as much as the taste.

Afternoon Hot Tea

I’ll often brew a hot tea in the afternoon and pour it into the tumbler. The double wall prevents the outside from getting too hot, which makes it comfortable to hold while I work. The sip opening on the lid is handy for hot beverages when I don’t want to use a straw.

On-the-Go Commutes

For short commutes, the lid’s silicone seal reassures me that spills will be minimized in my bag. I still try to keep the tumbler upright in a cup holder, but the leak-resistant lid reduces anxiety about accidental leaks. The set’s compact size fits many standard car cup holders.

Gym and Post-Workout Smoothies

After a workout I sometimes bring a smoothie in one of the tumblers. While it’s not a sport bottle, the straw and wide mouth make drinking thicker smoothies convenient and mess-free. I like having the glass as a reusable option that feels premium compared to plastic bottles.

Comparison with Alternatives

It’s important to compare these tumblers to other options I might consider, like stainless steel travel mugs, single-wall glass tumblers, or plastic reusable cups.

Compared to Stainless Steel Travel Mugs

Stainless steel mugs often provide superior thermal insulation and ruggedness. However, they can alter the taste slightly and lack the visual appeal of clear glass. I prefer the KEMORELA tumblers for beverages where I want to see the drink—matcha, layered lattes, or colorful smoothies—while choosing stainless steel for long-term heat retention on travel.

Compared to Single-Wall Glass

Single-wall glass is more prone to condensation and less insulated, which makes it less suitable for long sipping sessions. The double wall in the KEMORELA cups removes that worry and makes them more practical for desktop use and long sips.

Compared to Plastic Reusable Cups

Plastic reusable cups are lightweight and cheap but often retain odors and stain. Glass is inert and doesn’t retain flavors, and the premium feel far exceeds most plastic alternatives. I prefer glass for flavor purity and sustainability, even though it requires a bit more care to prevent drops.

Tips and Tricks for Getting the Most out of the Tumblers

I picked up a few practical tips during my testing that might help others get the most from these tumblers.

Tip 1: Use Ice Strategically

For iced drinks, use larger ice cubes or frozen coffee cubes to minimize dilution and extend chill time. The tumblers hold ice well and the insulation helps slow melting without condensation.

Tip 2: Maintain the Silicone Ring

Periodically remove and clean the silicone ring in the lid. Food or drink residue can accumulate in the seal, and taking it out to wash by hand ensures continued leak resistance.

Tip 3: Avoid Full Inversion in Bags

Although the lid is leak resistant, I avoid putting the tumbler fully upside down in my bag. Keeping it upright in a cup holder or compartment reduces the risk of unexpected leakage, especially when the lid has a sip opening.

Tip 4: Use for Layered Drinks

The clear double wall glass is beautiful for layered drinks—matcha with milk, for instance. The aesthetic presentation is an added bonus for me and makes at-home barista-style drinks feel elevated.

Final Thoughts and Recommendation

I’ve enjoyed using the KEMORELA 2PCS 20oz Double Wall Glass Tumblers with Lids and Straws – Insulated Borosilicate Glass Matcha Cups for Iced Matcha Latte, Smoothies, Reusable Travel Glass Cups – Leak Proof 2-in-1 Lid in my daily routine. They strike a practical balance between style, function, and sustainability. The double wall design keeps drinks at the right temperature for casual sipping, the borosilicate glass feels premium and durable, and the 2-in-1 lids add useful flexibility.

If you value aesthetics, want to reduce disposable cup waste, and prefer glass over plastic for taste reasons, I’d recommend these tumblers. Just remember that glass requires a bit more care than stainless steel or plastic, and while the lid is highly leak resistant for normal use, I avoid complete inversion in packed bags. Overall, this set represents a strong option for matcha lovers, coffee drinkers, and anyone who appreciates modern, reusable glassware.
