Connetix magnetic tiles encourage hands-on learning through imaginative, open-ended, STEAM-based play. Each tile has magnets ultrasonically sealed inside, allowing kids to snap them together as they build 2D and 3D creations. This sparkling 48-piece set is made with fine iridescent glitter, in a mix of squares and triangles to create shimmering patterns, structures and whatever else a creative kid can dream up. It's a terrific standalone pack or add-on to an existing Connetix collection.
