Coldest 20 oz Tumbler v2

My wife loves it

She uses her glow cup daily for work. The lid is fairly leak proof when I did accidentally tip it one morning as well. I have to add an ice cube otherwise it wont cool to where its drinkable until the afternoon os it holds heat well. It also glows, like glows glows like coming from outside on a sunny day it glowing visibly in the house.

Who needs a plain ugly coffee mug

I dont even use coffee mugs anymore. I use coldest cups exclusively. When home, I pull out one of these beauties for my coffee drinking experience. And with the non slip bottom I can leave my coaster behind.

I love the 20

I love these 20 oz cups. I use them for my coffee at home in leui of a coffee mug. I will say if you are making hot coffee and using the lid, you have to leave the vent open for a few minutes or the heat will push off the lid. But i dont even use the lids. I just make my coffee and drink straight from the cup. The 20oz cups dont stay hot as long as the 15 or the 24, but I am sitting home drinking it right away anyway. I use the 24oz for my traveling coffee that I need to stay hot longer.
