The Rainbow Set with 6 magnetic building blocks is perfect for small builds, quick play sessions, or adding a splash of colour to your collection. Featuring six vibrant colours, this set introduces the creative fun of Smartek in a compact form. Thanks to the Smartek system, all blocks connect seamlessly with existing non-magnetic building systems such as DUPLO® and LEGO®. With the innovative Smartek blocks, you can build in all directions and combine your creations with your own bricks. It’s magnetic building reimagined for unlimited creativity. Designed, invented, and patented in the Netherlands by Smartek.
