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

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.

The Tupkee double glass mug for hot or cold is my favorite. It keeps drinks hot long enough for you to finish. The drink with ice stays cold long enough in a hot car (TX) while doing a 90 minute shopping trip at Costco. It's easy to clean, and yes, I have 3....

it’s a great glass for hot or cold drinks very functional

Loving it so far. Really like that you can remove all the silicone to wash properly. This 14oz size fits nicely in my hand. Only tried with water so far, everything tastes better in glass. Will update my review as I get more usage.Update: I replaced the silicone sleeve with a different material cause it was easier to remove for cleaning. I still love everything else about this cup.

This glass seals well. I was surprised by the mouth feel when drinking from the top. The hole is not large enough for a straw, but it is a joy to drink from it. Unfortunately, the glass fell and shattered. I'll get another one.

Sleek and easy to carry. Could sweat a little less, but otherwise good quality. Good size. Fits my car and my small hand.

This mug works well and has good construction with no leaking. But, the mug does not insulate well. there is a hole in the bottom of the glass, so the air between the the walls of the mug gets warm/cold, which warms or cools the glass.

This is a beautifully blown glass travel mug, and does a good job keeping hot beverages hot. However, as others have noted, it is not leakproof. If it tips over, the beverage will pour out of holes in the top of the mug. Additionally, the lid does have a tendency to separate out of the base, especially when heated. This causes the mug to leak from the side when drinking. I added a silicone band to cover the seam between the lid and the base. This completely prevented the lid from separating from the base, and stopped the cup from leaking. I used JOVITEC 12 Pieces Rubber Bracelets, Solid Color Silicone Wristbands, Multi-Pack Blank Wristbands Bracelets for Events Rubber Bands Party (Black). A better (wider) band is Grippy-Bands Colorful Water Bottle Grip Kit (both available from Amazon).
