The red Solo cup, the cup that goes hand in hand with drinking beer. Why red? Why not? Anyway, now you can enjoy drinking out of a red plastic cup even when you’re drinking out of a can with the Red Cup Koozie. Sure you could have poured your beer out of the can into a regular red cup but it wouldn’t be insulated and somewhat spill proof like a can in a koozie is. Solid party accessory. Just solid.
