This fun-filled wooden rocking ring stacker for children is designed to develop their hand-eye coordination through fun and hands-on play. Children are encouraged to place the wooden rings in the correct sequence and stack them on the tower. That is quite a challenge, because the tower keeps rocking back and forth. Keep on trying, you can do it! Minimum age recommendation 12+ months Product dimensions 10,7x10,7x22,5 Material Pine, wood, MDF, water-based pain
