Foam Koozies work great for personalized coolies. They are hard and firm and insulate cans perfectly. Coolies can come in many different materials but foam is the oldest most ancient coolie style out there. It is almost like the Aliens brought them here from the planet Titan. Coolies are just to advanced for to be a human invention. You probably won’t believe this, but we once had UFO fanatics that had ordered a 1,000 coolies with an unidentified flying object on one side and then on the other side it said “E.T. Foam Home”. The koozies were used to a Party out in Arizona where they were trying to phone in Aliens from the mother land… Planet Titan. The Party planner was hoping to give a coolie to the aliens if they happened to have an encounter. She thought they could use it at a probe holder.
