Shapes stick to the bathtub wall easily once they are wet so you can spell out whatever you want or just let your child’s imagination run wild. The colors are very bright which is always great for a children’s toy. The bag is pretty good sized. It allows the shapes to dry between uses. It can hold more toys with this set and it would hold all of it. Kids learn colors, numbers, letters, counting, spelling, sorting, and other wonderful skills with these shapes. Each soft piece is smooth on one side and textured on the other side.
