The first Caustic Casanova Koozie, designed by Jase Harper. Jase is Australian and has informed us they're called Stubbie Coolers down under. These blue and yellow beauties are super high quality foldable neoprene koozies and they fit snugly around any can or bottle. Just as our shirts are the most comfortable and our stickers the most satisfying to stick, this koozie will envelop your beverage to your utmost satisfaction. CC doesn't cut corners, especially not with the koozies to which you entrust your precious beers, ales, ciders, meads and soda pops.
