Montessori Object Permanence Box with Tray is a beautifully crafted Montessori toy designed for infants aged 9 to 18 months. This early learning material helps young children understand the concept of object permanence — the idea that objects continue to exist even when they are out of sight.
As the child places the ball into the hole, it disappears and rolls out into the tray, creating a cause-and-effect experience that stimulates curiosity and brain development.
