Disposable and Single-Use Product Design Tag Tag Mark disposable cups by Jiani Zeng TAG TAG is designed to distinguish one’s disposable cup from others to reduce waste. Both the paper and tag are made from food grade materials. Paper cups in events are often thrown away if mixed up with other people’s. But no one really cares about such waste. Instead of using a marker and pen to sign your name on the cup, you can simply scratch some tag off and make any pattern you like to distinguish yours from others. So after the break between meetings, you can still find your cup.
