Super-Snap is designed for easy, fast and safe contouring, finishing and polishing of all microfilled and hybrid composites. The kit comes with an elastic silicone shank mount for easy placement of the disk onto the mandrel. The disks are manufactured without a metal center, and their flexibility and ultra-thin design allow easy access to interproximal areas. The Super Snap Rainbow Technique kit comes with disks in two sizes and four grits (silicon carbide and aluminum oxide).
