At nearly every party there is one problem. Is that my drink or your drink? Did I sit my drink here or here? The lost cup leads to waste and annoyance. Etch-It cups solve the problem. The plastic cups come in various colors and an area to claim the cup as your own. Peel back the white paper to reveal the etchable black surface that require neither pen or marker...use your fingernail to sketch your name (or any message!) on the cup and worry no more. Problem solved!
