Object Permanence Box with Tray Three Balls for 6-12 Months Babies (T-I040-1F)

An object permanence box is a classic Montessori material that is introduced to infants once they can sit up independently, at approximately 8–12 months of age.
An infant places a large wooden ball into a hole located on the top of the box. The ball momentarily disappears into the box, but then reappears as it rolls back out into a tray where it is then easily retrieved by the infant. A baby who is still actively developing an understanding of object permanence will often engage in long periods of repetition with this task until mastery is achieved.
This material aids in the child's development of object permanence, while also honing their hand-eye coordination, fine motor skills, focus, and concentration.
