Yes, the red cups at the party are iconic but they don’t do much for keeping your beverage cold and your hands dry! We’re guessing it’s because of the little scientific thing about your hand being warm and there’s only a thin slice of plastic separating your body heat from your beverage.
With our Red Cup Koozie, you can place your beverage can or bottle into an insulated red cup to keep it ice cold and your hands warm and dry!.. while still looking cool!
Let’s face it, it’s never a real party without the big red party cups and you’re keeping that dream alive… till someone yells out, “who let my python out!?!”
