Cubo Montessori Box Starter Kit is a 3-in-1 imbucare box featuring the ball and coin drops, including the modular box. Our Starter Kit teaches the child that an object is still there even though she cannot see it through Piaget’s theory of object permanence. The lids and parts can be changed to suit 3 different play patterns that progressively learns this theory: a ball drop using half lid, a ball drop using full lid, and a coin drop. Our Montessori boxes are modular, minimal, eco-friendly, and curated by an early learning professional. Let’s play in so many ways with Cubo Montessori Box!
