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