20 oz Double Wall Glass Tumbler

I like the 20 oz size. I use it for Coffee in the Morning and Energy Drinks with Ice in the Evening.It may be a little large for a Lady. It is made of glass and therefore is fragile so it must be handled with care like any other expensive glass.

Amazing design. Extremely functional but also beautiful and elegant in its simplicity. The double walls protect your hands and keep your beverage at temperature. The coffee-sipper style lid works exactly like a plastic one would but feels a lot nicer on your mouth. Rarely, certain substances can make the lid want to pop out, but wiping the rim and silicon rings clean will allow it to attach securely again. I've only noticed that happen with foamy coffee beverages, it never happens with plain coffee, tea, or water. My one and only complain about this cup is that because of the double walls, it's very wide and won't fit any of the drink holders in my car. Not a big issue, though, as it's comfortable enough to hold between my legs if I'm driving. I had the 14oz version of this cup but I ended up buying the 20oz version because it's harder to find places in the USA that sell teas and coffees in 14oz sizes.As an added bonus, every time you use this cup instead of a disposable cup, you're saving trees, reducing carbon emissions, and reducing the amount of microplastics entering our water.

***update to the below. My review below was written on day 1 of having the cup. On day 2 the inside cracked a broke when hot coffee was poured into it. All around this new cup is disappointing and nothing like the 14 ounce cup. Very unfortunate.First of all, I want to say I am a huge Tupkee fan. My wife and I love the 14 ounce travel mugs but its downfall is it doesn’t hold a venti sized drink, so when we saw the 20 ounce cup we were very excited. It is made way too big. It is so fat it’s hard to get a good grip on it, especially for my wife who has smaller hands. I have a 2023 Ford Raptor truck and the cup doesn’t even come close to fitting in the cup holders. The purpose of this cup for me is to have while driving, so this is a huge drawback. It is also very heavy. I don’t like paper cups because they are lined in plastic, so Tupkee’s 14 ounce glass tumbler is great but just a little too small. A sleeker and slightly lighter cup in the 18 to 20 ounce range that fits a cup holder would be a dream. For now, this one falls short of that dream.

After buying 6 other glass water cups, this is the one! It has the right spout. It holds a good amount of water. It’s double walled so my ice lasts. It has a wide mouth so easy to fill with ice. It has a glass top. This is the cup I have been looking for. Glass does not alter the taste of my water. Thank you

The Straw Lid for this cup has a major design flaw. It seals very well, perhaps too well, and putting on the lid will cause a spill as there is nowhere for the air to go except through the straw and it will force any liquid you use through the straw first. Using the glass straws will cause the cup to burp and gulp when you stop sucking as the straw is the only way for air to be replaced in the tumbler. It needs a small hole in the lid somewhere to prevent this from happening, as the lid that comes with the tumbler does.

I have been using this for the last couple weeks and i have been loving it.Only one drawback was the silicone base can easily fall off otherwise this product is amazing.

The media could not be loaded. Tea & coffee just taste better in glass. For work I place in ref. then in morning off I go. It durable, functional, cold or hot it stays that way, leak proof with the cap on the straw. Best of all my tea taste great. As you see I have small hands. So Next on my list is the handle that they have to purchase.

These glass mugs are super for thise with metal allergies who don't use plastic as well. No leaks. Sleek and stylish. Stays hot. The larger one doesn't fit my car, but is good for my desk. Quality design.
