Introduce toddlers to magnetic construction, sensory exploration and social-emotional expression. Connect large and small magnetic rods or combine them with the over-moulded metal ball connectors. The variety of rod styles creates a unique structural, rounded and acoustic building experience. Encourage magnetic, auditory and tactile exploration through patterning and 3D construction. Perfect for toddlers to exercise their auditory, fine and gross motor and STEM engineering skills. Clean with a damp cloth and mild soap only. Air dry completely.
