I just did some research and apparently a “party” is a “social gathering especially for pleasure or amusement.” And at these parties, people drink any number of drinks from any number of cups. What happens, though, when you set your cup down inadvertently next to someone else’s? How do you know what drink is yours? Designer Jaehyung Hong has the answer for us.

These cups come with a series of letters and other symbols along the bottom rim. It’s up to you to decide exactly what symbols you want on there. Make it sufficiently unique and you’ll avoid that whole “is that my cup or yours?” scenario. Thank God Hong’s on our side!
