KNEE GEL PACKS - Back IN STOCK - thanks for your patienceSquid Gel Packs use a proprietary gel formula that allows the gel pack to maintain its shape. The gel pack is able to conform specifically to a treatment area for maximum results. The gel pack freezes at a lower temperature than water, which allows for a shorter, more effective treatment than other methods. With Squid Gel Packs, there is no melting or mess, so clean up from a treatment is a breeze.
