$1 Impressive Cup!

I paid a dollar for this cup. I didn't think it would be anything decent just a simple cup for my morning coffee. It is actually pretty awesome. Thick solid plastic. Very good design. I will use this a lot. No more buying endless paper cups. I can't fully review this item as I only drink cold iced coffee, but I put it in the freezer with my iced coffee to make it super cold and it held up to the test. I love it! The little flip lid for the mouth piece is great to help prevent spilling or bugs flying in it being outside. Cool cup for a GREAT price! Good job...

Nice Cup

great for short trips in the car or just having something to drink through the day if you're in the house or outside. the lid closes pretty tightly so you don't have to worry about any kind of bugs getting in your cup or any type of debris if you're doing yard work etc. would make great stocking stuffers with maybe a few treats inside. :)
