Grensuny thermoplastic splinting material becomes transparent when heated and super strong when cool. It defies fingerprinting and cools to a beautiful smooth finish. Grensuny product is coated to prevent accidental self-adhesion, but can be easily welded to itself by pressing and rubbing two surfaces together. It resists unwanted stretching and has excellent memory. Simply reheat and reshape as many times as you like. Best water bath at 65-75 centi degree. Available in a variety of sizes, colors and perforation patterns.
