Play, Stow, Go! Beyond the shape-sorting and fill-and-spill play, the shapes also come apart into 2 pieces for matching and double the shapes to sort. For easy storage the kitty collapses down flat to fit in a diaper bag and stores the pieces securely inside for easy portability. Expands to 4.5 inches when ready to play and the close lid helps to keep everything in place when your on the move. Recommended for ages 18 months and up.
