There are few things grosser than sticking your hand in someone's chewed up gum. That is unless it's helping you figure out which glass is yours.
Stuck Up Drink Markers aren't real pieces of chewed up gum, that's nasty, even for us, but their rubbery sticky surface is perfect for telling whose glass is whose at a glance.
The drink markers come in a variety of colors and are molded to resemble chewed up bubble gum. It may take a few drinks before the gag reflex stops getting triggered, but you can party assured that nobody will forget which drink is his and need to bug you for a fresh glass.
