Mainstay 40 oz tumbler

This tumbler is double insulated so it keeps the water or other liquids cold for a long time. I use it everyday. It also fits in my cup holder in the car. Filling up is easy.

Love it!

Gave this item to a friend. And she raves about it. It's helping her get her water in and fits in the car cupholder. And of course she loves the color.

I absolutely love this cup, love the color! only problem I had, if I bought another one I will go smaller because this one can get kind of heavy once it's filled up.
