Adena Montessori Object Permanence Box with Tray
A true Montessori classroom staple: a baby drops a ball through a hole, watches it disappear, then sees it reappear on the tray below. It's one of the simplest ways to introduce object permanence, and it's a genuinely popular pick with over 3,000 reviews backing it up.
