Stack these pieces together to make a real rainbow, or jumble them up for all kinds of different shapes. Each piece is solid wood and finished with non-toxic water-based paints and lacquer. The set includes six rainbow pieces plus a smiling sun to balance on top. The finished rainbow measures 21 cm wide by 14 cm high (about 8.5" x 5.5"). Great for size and colour recognition, or as an adorable decoration for baby's room.
