FantaColor Modular 4 makes it fun to create big and beautiful mosaics! First place the 4 perforated boards together in any way you want and connect them together using the red square pins. Push the colored pins into the perforated board and follow your imagination. Children can make their own mosaics or follow the examples from the sample booklet. To start over, simply turn the board over and push out the pins. The set comes with 600 pins in different colors and 4 different sizes (5, 10, 15 and 20mm). Excellent for hand-eye coordination. Suitable for children from 5 years.
