Wahu Phlat Ball Classic is a unique sports toy that transforms from a 9 (22.9cm) flying disc to a 6.2 (15.7cm) fun ball when thrown. Its time-delay transformation adds a twist to the classic outdoor game of catch. It 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 Classic - Disc: 9 diameter (22.9cm), Ball: 6.2 diameter (15.7cm). For 1 or more players, ages 5 and up.
