Wahu Phlat Ball Flash is a unique sports toy that transforms from a 9" (22.9cm) flying disc to a 6.2" (15.7cm) fun ball when thrown. It features bright LEDs with flashing light effects for added fun at night and a variable time-delay transformation that adds a twist to the classic game of catch. Wahu Phlat Ball Flash also packs flat, so it's easy to slip into a backpack or suitcase. If it lands on a sloped roof, it pops open and rolls right off - it's not a flat ball for long! Throw a disc...catch a ball! Includes 1 Wahu Phlat Ball Flash Black - Disc: 9" diameter (22.9cm), Ball: 6.2" diameter (15.7cm) - batteries included. For 1 or more players, ages 5 and up.
