Shape up your sorting skills with the Rainbow Stack 'n' Sort from B. toys! This educational puzzle comes with a wooden board, a resealable holographic pouch, and 14 geometric shapes for kids to stack and sort with. The pieces are divided in colorful pairs, each one with a solid and a translucent shape. Children can discover squares, circles, pentagons, stars and much more! All of the pieces are smooth, vibrant and easy for tiny hands to hold.
