The WYLD Cup is designed to look just like the iconic plastic cups that have fueled parties for a generation, but we've given it a reusable, eco-friendly, high-performance upgrade. The Official Party Cup is made with insulated stainless steel that will keep your drink ice-cold (or hot) for hours. Pour in the beverage of your choice and pop the lid on top. Plus, the bottom of the cup is ringed with a non-slip rubber base to hold your cup in place, even while the party rages around you.
