Featuring eight bright colours, this pack includes three different sized squares designed to neatly nest together to take open-ended play and STEAM learning to a whole new level. The large and standard portal tiles - with their unique open-frame design, unlock innovative ways to engineer and build with multiple magnetic connection points on the inner and outer edges; while the mini-squares showcase the CONNETIX Smart-Spin technology, allowing magnets to rotate up to 360 degrees within the tile to build in new directions and discover exciting construction possibilities.
