Throw a disc, catch a ball! Phlat Ball Jr. is a smaller version of the unique sports toy that transforms from a flying disc to a fun ball when thrown it's like a Frisbee ball. The Junior version comes as a 5. 5 inch disc and transforms into a 4 inch ball. Packs flat for easy transport, so it's the ideal travel game! If it lands on a sloped roof, it pops open and rolls right off it's not a flat ball for long! It's great outdoor fun for boys and girls! Ages 5 and up, 1 or more players.
