Slip the Blue K2 Can Chiller by Built over a canned drink to keep it cold for up to 8 hours. This double-walled, vacuum-sealed chiller features an innovative, Patent Pending bottom with tabs that hold the can in place while drinking. The soft rubber footing keeps the chiller stable on tables and won't scratch surfaces. Made from durable, food-safe stainless steel and rubber that stand up to daily use. Simply press on the bottom of the can through the opening in the bottom of the chiller to remove. Hand wash with warm water and a mild detergent.
