I love my Java Soks! These koozies are great! It drives me crazy how people use styrofoam cups as koozies. It’s so bad for the environment. Java Soks fit Dunkin Donuts cups perfectly. I wash them in my dishwasher and the colors remain vibrant. I have them in every color. My friends make fun of me until I give them one, and then they’re hooked, too. Do yourself and the environment a favor…get a Java Sok (or two…or three).
