What makes a Gertie ball so wonderful?  It's the soft, squishy, huggable feel!  Gertie Balls have a unique, slightly-sticky surface that makes them extra easy to throw and catch - even for the youngest kids. Simply inflate the balls to the desired size and skill level.  Whether they are full and bouncy or soft and squeezable, Gertie balls are always light and gentle, for both indoor and outdoor play.  And it's the only ball that travels small!  Deflate flat for easy packing, then inflate quickly with the included straw.  Safe for all ages.
