Wooden box with two compartments, flip lid and coin
This box with a coin and a slot on the lid is the third, more advanced version of the object permanence. When your child drops the coin in the slot, turning the wrist to fit the coin in the right way (fine motor practice), and flips the lip, he/she will discover and learn that the coin is still there even if it was hidden for some time.
Introduce this toy when your baby is approximately 11 months old.
Box: 29x15x11 cm
Coin: 5 cm
