Connetix Tiles contribute to the development of fine motor skills, spatial awareness, identification of common shapes, and hand-eye coordination – and they’re simply beautiful.

The tiles are made from ABS non-toxic, BPA-free plastic. They are compatible with both Playmags and Magnatiles. We recommend using a damp cloth without chemicals to clean your tiles. We don’t recommend placing them in water as the magnets may rust. Although each Connetix tile is ultrasonically welded and includes rivets for extra safety, your child’s safety is paramount and so they are recommended for play from 3 years and up.
