This ball is molded from a durable, textured rubber that gives dogs a firm surface to grip while running and carrying. A photoluminescent pigment built into the rubber absorbs light and releases it as a visible glow, so the ball remains easy to spot on a dark lawn or trail. No batteries, cords, or switches are involved; exposing the ball to any bright light source charges the glow effect. The rounded shape and sizing are built to match Chuckit ball launchers, which are sold separately, for extended throwing distance and less handling of a slobbery ball. Between play sessions the surface rinses clean with water. It is intended for supervised outdoor or indoor fetch play with dogs.
