Our popular magnetic building block set enhances your child's brain development through play. The brightly colored, magnetized, quick-connect tiles allow children to intuitively build their own designs simply by promoting problem solving, hand-eye coordination, spatial awareness and fine motor skills, all while playing! Featuring 71 blocks in different shapes, including columns, slopes, funnels and U-turns, the 3D race track lets children use their imagination. Compatible with other PicassoTiles sets, it can be expanded into infinitely larger combinations.
