Add extra hands-on variety to your modular activity board with a three-tile refill pack designed for sensory and fine-motor play. Each pack includes three snap-on tiles that slot into the activity board to create new tactile, visual and cause-and-effect experiences — think moving parts, textures, and little mechanical surprises that encourage exploration and coordination. Swap tiles in and out to build new combinations or toss a few in a bag for on-the-go entertainment. Packs arrive in assorted packaging colors; you can request a specific style at checkout or opt for a surprise assortment. A simple, extendable way to refresh and expand a busy-board playset for young children.
