Double Wall Stainless Steel Vacuum Tumbler Picus 30 oz Travel Mug [Crystal Clear Lid] Water Coffee Cup For Home,Office,School - Works Great for Ice Drink, Hot Beverage

It is not leak proof because the mouth piece starts open. But it cleans completely compared to the others with the slide top that you can't clean all your beverage out of.

The cup keeps cold drinks cold and hot drinks hot, but the lid does not fit tightly rendering the entire thing useless.

I loved this cup!!! I used it for cold drinks and it stayed cold for a very long time! !!

Excellent Product
