The Superdisc's soft, rubber edge provides a great grip for strong throws and remains smooth to catch even after landing on pavement. Conventional discs often develop sharp scratches and burrs. Made from non-toxic materials, the Superdisc's soft edge is also kind to a dog's mouth, making it the disc of choice for many professional dog disc entertainers. Floats in water. Size: 10 inch diameter. Available in assorted colors. Ages 8 and up.
