BasicBox is an original sorting box for ages 18 months and up. First, choose 1 of the 5 boards, each with a hole matching the shape of a wooden piece: a square, a circle, a triangle, a flower and a semi/circle. The adult inserts it in the box and the child finds the piece that matches the hole in the board, slides it in and lets it drop into the box. The pieces come out again easily so you can start again. The bottom of the box is lined with felt for less noise when the pieces drop. The bottom of the box slopes so the pieces come out again easily. Everything fits inside the box. Lets your child focus on 1 shape at a time.
