Introduce light and color exploration, along with early STEM skills, through the organic and layered builds of Grippies® Windows. Over-molded metal ball connectors join colorful, secured magnetic panels to create 2D and 3D builds. Tactile grips and over-molded plastic are soft and easy for little hands to hold. Watch your young builder discover magnetic principles, properties of light, and color recognition through multiple building and patterning activities. To care for Grippies, simply wipe clean with a damp cloth and mild soap and allow to air dry completely before continued use. To prevent damage, do not completely submerge in water or put any Grippies pieces in a dishwasher or washing machine unit. Available in 16 or 24 piece sets. Age: 18 months+
