Tupkee Double Wall Glass Tumbler - 8-Ounce, All Glass Reusable Insulated Tea/Coffee Mug & Lid, Hand Blown Glass Travel Mug - Cyan

To replace my paper cup addiction I was looking for something to have coffee and tea in with a lid. I already have a stainless steel travel cup but just wasn’t using it at home so much. This is glass so no metal taste. No microplastics leaching into my drink. I LOVE IT! So glad I found it in a Reddit conversation!!!!! Great quality, does not leak, great feel and weight, nice design. The mouth part does not close/seal like a thermos or one designed for travel but you can still take it with you if you keep it upright. Just a small hole for liquid to come out for drinking. So glad I found it. Saves money -no more buying hot cups, saves environment, no microplastics leaching! Highly recommend it!

This is a very nice, well constructed, glass tumbler. It feels good to hold. And very nice to drink from. The silicone pieces are very easy to put on and take off. The lid is very easy to fit and is good and smooth to drink from. I use it in the house without the lid most of the time. More heat will escape but I like the open experience. The only downside to this, is it's potential durability. It appears very fragile. That's why I gave it 2 stars. The base and sleeve is a nice addition for protection. I knew this going in and expect to eventually break it but that's okay. If you like to drink from glass, then you will like this cup. 5 stars overall.

Wasn't sure about this when I first received it because I didn't think it kept my coffee warm long enough, so I found I needed to not leave it sit and go do other things. After using it a couple times, I really started liking it. Easy to clean and it fits nicely in my hand. It is glass so I treat it gently when washing it. I bought the blue one and it's a very nice color. It's on the small side but it's a good size for not allowing the coffee to cool down too much. It was a bit pricey but I think worth it. I'd buy another one.

I've ordered several of these tumblers and love them, however the last one came with a damaged rubber ring in the ring. Paying return postage and packing it up to send it back would be too much trouble so I'm using it without the lid.

I love purchases that I now I can live without! This very thoughtful and elegant design is well wrapped and secured with a silicone band in the mid-section and encapsulates the bottom. The mid-section stays cool to the touch with a very hot beverage inside the the double walled borosilicate glass walls. The weight and balance are perfect. Of course, I would suggest bouncing it off the walls or floor, it is sufficiently sturdy for my life. It hand washes very easily or washes perfectly on the top shelf of my dishwasher. Sipping out the slit on the top edge takes no learning curve and I can keep my eye on my phone or other screen when drinking. Best of all my office kitty is forced solely to drink from her bowl of water and not share from my glass or cup! I most highly recommend this splendid 8 oz cup.

The mug isn't exactly 8ounces (-maybe it's 9.9-10) but nonetheless, I have enjoyed using this glass travel mug. The mug is easily cleaned and the gasket on the lid is durable.I appreciate having an insulated vessel to enjoy my americano in that doesn't have any taste residue due to paper, metal as other travel mugs can have.

I was apprehensive purchasing this as it was glass however, after using this for several months I find it to be more pleasing than some of the plastic mugs I have purchased. Having the double glass wall means no hot hands and keeps the coffee or tea hot until the last drop. Now most important, I have dropped this several times and has not broken or cracked and am very pleased.

Wow this was so much smaller in real life than what I needed. Would work great for a child size drink, however!The glass lid didn't sit well upon the cup. Once you put the glass lid on, you could literally watch it levitate up and off the cup?!?! I'm no engineer but perhaps the silicone gasket is too thick/large that it unseated itself 100% of the time.Once you get these 2 issues locked down, you golden cuz it's very well made otherwise. Quality of the glass is solid.
