These cups are a great size and have a clear lid to make sure you don't spill your drink on yourself or the floor. The bottoms are great because you don't have as many accidents with the rounded bottoms as you would if the bottoms were straight down. The drinks stay colder than they would if you had a plastic cup. They are a decent size for your drinks. I haven't tried to drink hot beverages from it but I have my cold drinks. The surface of the cup is flat and plain so if you wanted to decorate it you could. You can make it your own with a design or words.
