The Coolie is the newest in the Chunky product range. Use it to keep your can or bottle of beverage nice and cold until you can savour the last drop. It is made of double walled stainless steel with a tactile 3D printed design on the outisde. You can even use it as a drinking cup if you like. It will still keep your drink cold. The silicone ring keeps your bottle or can secure in place but you can also use it as a non-slip base when using as a cup. Great for boats!
