Thank you for viewing. Pita Rico Suction cup educational blocks. You can stick them on mirrors and windows to play. The sound when you peel them off is refreshing. You can create various shapes and enjoy them with your imagination. I bought it new, and my child used it for a while, but they stopped using it, so I am selling it. Some of the suction cups are slightly yellowed (white, light blue short ones, and the fish. Please refer to the photos), but I think they can still be used. There are scratches on the blocks. Please understand that this is a used item before purchasing.
