I bought this thinking I'd play with my child, but it didn't really click with them, and they've grown up without using it much (^◇^;) It hardens with water, so kids can play with it safely on their own! The recommended age is 6+, but you can put the illustration sheets in the square frame, so even younger children can enjoy it together (photos included). The number of beads is varied, but it includes round beads, sparkly beads, and polygon beads. I'd be happy if someone could use it^_^
