Tupkee Double Wall Glass Tumbler - 14-Ounce, All Glass Reusable Insulated Tea/Coffee Mug & Lid, Hand Blown Glass Travel Mug - Cyan

This tumbler is exactly what I needed! I think beverages taste better in glass, and I've been searching forever for a double-walled container that didn't have a plastic lid or straw. This fit the bill perfectly.The lid is very snug and doesn't leak, which is great. I feel confident that this is going to save me from splashing coffee on myself when I'm in the car, and it fits well in my cup holders. It does have a very hole so you can drink from the glass lid, so if you tip it it will spill through that hole, but the seal where the lid meets the cup is very tight. It doesn't leak.The only con is that the design throws off the center of gravity because it is tall and narrow with a wider top than base; it's a tad unstable. Make sure you are sitting it on a perfectly flat surface and be very careful! I did tip it over accidentally on my granite counter, but it amazingly did NOT shatter or chip when hitting the hard surface. So, it seems reasonably sturdy, as most borosilicate glass is compared to regular glass. Because it didn't chip or shatter, I am highly confident this is indeed borosilicate glass (commonly known as Pyrex).I wish it had more colors than purple and black. I would like to buy this for other people but everyone wants their own unique color!

This is my second purchase of this tumbler. Three years ago, I purchased my first one and was very careful of it until I accidentally knocked it off a side table. Interestingly, the outside glass remained more intact than the inside, thinner glass, which completely shattered, but the broken glass was more contained than I would have thought. Obviously, a glass tumbler will not survive a fall to a wood floor. I was happy to see I would be able to replace it and purchased a 2 pack. I like the clean look of glass. My previous tumbler looked like new the entire time I had it. I have not had issues with the lid popping off. You know the silicone seal is seated securely when the glass lid clinks against the glass tumbler when you put it on. With this being a 14 oz. tumbler, there is room for 12 oz. of coffee as well as sweetener and creamer. I have found that this tumbler does not keep my coffee as hot as metal travel mugs or for that length of time, but I usually only use it at home and when I know I’ll be drinking my coffee in a shorter amount of time. I don’t know how to judge the leakproof part of the review. It won’t leak unless it falls on its side, and then it might leak from the small sip and vent holes in the lid that are always open by design.

This product is awesome 👌 I am cancer surviver and I always look for products that are less toxic in the market. This product has it all. It is a clean material and that facts reflected the flavor of the beverage that contains, in my case is coffe, the flavor is so different when I drink it from other tumblers, stainless steel for instance. The fact that the lid is glass makes it even better since keeps my coffe hot for longer and doesn't change the flavor as well. I love it!The only detail is the thickness of the borosilicate flass is thin. I don't take it with me in my car because I want it to last for a while. It would be perfect if we're thicker of course I would pay the price because it is worthy.

This is very comfortable to hold and has a rubberized section to prevent item from slipping away. It is attractive, has a comfortable sipping top, "that will only leak if you put the gasket in upside down." The container did keep my tea hot, and I like it. Unfortunately, it Said "hand wash." I had washed it, and was trying to refit the gasket back into the lid, when the top piece slipped away from me and crashed into smithereens on the tile floor. I like the product and will try to contact the company that makes it, to ask if I may purchase a new top.

I've been using my Tupkee double wall 14oz tumbler for about a month now. I couldn't imagine how much better it is compared to the stainless and ceramic ones I used in the past. I never thought about a glass tumbler, but when I needed a new tumbler, I came across this one and decided I'd give it a try. And I'm so glad I did. The lid is great. It stays tight and sips really good with no leaks. The Tupkee keeps my tea pretty hot until I finish. The glass is tasteless and nothing sticks to the glass making clean-up as simple as a good rinse. I highly recommend the Tupkee tumbler for anyone looking for a great mug.

I was looking for an all glass cup to avoid the usual plastic lids, and loved the taste of my morning coffee for the 14 days this thing survived. I saw all the reviews for fragile and thought it wasn't an issue. Handwashing, reasonable caution, I've kept phones alive with no case. I had the tumbler set on a counter, barely tapped the top with an elbow, and next thing I know it has shattered in hundreds- literally hundreds- of slivered pieces. After cleaning up the main shards, I spent well over two hours getting the tiny glass crystals out of the floor, which I kept finding when they poked into my feet. Worst modern glass cleanup I've ever had.

These glasses are excellent with one major caveat which I didn't know - they break rather easily. One broke the second day when a washed dish slipped on it while drying. I don't see anywhere it says "Fragile". Learn that and they are excellent glasses!

I absolutely love my Tupkee Double Wall Glass Tumbler! It’s stylish and keeps my coffee hot and you can’t beat drinking coffee out of a glass mug! The tumbler feels light yet sturdy in my hand. Easy to clean and surprisingly durable, it’s now my go-to for home and on-the-go. If you're a health-conscious coffee and tea lover like me, you’ll definitely appreciate this tumbler! Highly recommend!
