Encourage spatial and social emotional play with toddler STEM toy Grippies® Stackers. Assemble communities with interlocking magnetic 2D and 3D builds or nest the expressive cylinders in between textured X-shaped blocks. Tactile grips and over-molded plastic make these secure magnetic construction toys soft to touch and easy for little hands to hold. The stimulating blocks and cylinders encourage patterning, balancing, and matching skills with four bright colors and textures. 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+
