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’ss 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! And if it lands on a sloped roof, It pops open and rolls right off-it’ss not a flat ball for long! It’s great outdoor fun for boys and girls ages 5 and up. 1 or more players.
