KeepCup Brew Cork - Reusable Coffee Cup Tempered Glass and Natural Cork, M 12oz/340ml - Black

I really do love this cup. Was turned to it by Lead Free Mama. The cork ring lets you hold onto the cup without having to touch the glass and get hot or cold or wet. The lid has a closure that works well, I’ve dropped it a few times and it doesn’t spill with the thing closed, also pretty durable. But please make sure the lid is on all the way. I went to pick it up in the car and only grabbed the lid and it wasn’t secure and spilled everywhere. Also, it says not to remove the cork ring, but if water gets trapped under there it can start growing green mold. It can get damp and be ok, and if you do have to remove it to clean the ring and under it, I found it’s easier if it’s damp, to come off or go back on. It is a cup made for someone who is willing to spend that little extra time on it, but worth it imo. It is not an insulated cup tho. It will not keep your drink same temp. I drink iced lattes and don’t mind if the ice melts before I finish it.

I absolutely love this little cup! It is the perfect size for a regular cup of coffee and it's so cute. I use this daily and it would make a perfect gift idea! My coffee stays hot and cleaning is a breeze! Great quality!

Very nice

Good for hot, excellent for cold beverages. Feels good in-hand, easy to hold and fits in cup holders. The size and shape are perfect for the several Keurig machines I've used it with. You can fill your glass with ice, use the iced function, and have just enough room to add your cream, honey or other favorite condiments. Having the cork band means you do not have to worry about burning or freezing hands. There are only two little issues I could find to pick on. 1) the lid can leak at the hole in it's center where the sliding cover unlocks for cleaning, but only with hot beverages, not with cold. 2) hot beverages don't stay hot as long as I'd like, even with the lid on (after all, it's glass, not vacuum sealed aluminum). These two small trade-offs are worth the benefit of reaction-free and flavor-neutral glass. This has become my favorite mug, used daily! One request, please offer a royal blue 💙 lid. Go Cubs!

I did not use this specific one, but had bought and used the same cup in a different color. This Keep Cup glass coffee cup was nice and substantial. The coffee stayed hot for some time using a neoprene sleeve. The grip was easy and the cork helped holding the cup when hot. However, it is pricey but good quality.I did not like that the cork was not removable becasue I could not microwave the glass cup with the cork on, when the drink eventually turned cold. Also I did not like the fact there is a plastic lid that you have to drink from, with your lips touching and eating microplastics. I just removed the lid when drinking at my destination but not while driving.I did constact KeepCup asking if they could make one with a removable cork or silicone sleeve. They offered the plastic doulbe walled cup with a removable silicone sleeve, but then if I wanted a plastic cup for my coffee, I wouldn't have purchased this expensive glass cup.

Love this cup for my tea in the go!

I hardly do reviews but had to for this one... It's the perfect office tea glass. Some complain about the position of cork band but I find it perfectly placed with middle, ring, and thumb placed on cork with index finger place on lid... Comfortable and no hot surface to skin. Ease of clean is a plus. No spill or leak so far. Overall a good purchase.

After a while, the lid leaks much from the sip hole when closed. But overall, it's better than drinking from a paper cup.
