Add the top sleeve to cover and insulate bottles completely. The stainless-steel exterior looks great and protects from drops and spills. The Icy Bev Kooler is designed to fit most major beer bottle brands (12 oz. bottle size). It works with Budweiser, Miller, and Coors products. Even tall Corona bottles will fit just fine. The black, circular sizing disc with built-in opener can be placed inside the base to accommodate shorter bottles, such as Blue Moon and Heineken. It also will fit some glass soda and mineral water brands.
