Unlike other ice rollers (made with plastic wrapped around gel or with stainless steel), this roller is made with solid aluminum, which helps keep it icy cold longer. The handle is made with silicone for a more comfortable - but sturdy- feel. The Skinny Confidential Ice Roller is designed to be 20-30% bigger than any other ice rollers in the market - from the size of the ice roller to the length of the handle. Has a fingerprint placement guide, for better grip.
