Unleash endless creativity with the Rainbow Ultimate Set, a vibrant collection of 78 magnetic building blocks in six dazzling colours. This premium set includes 54 Smartek CUBEs for classic magnetic building fun and 24 innovative MEGO blocks for limitless expansion.

The unique MEGO A and MEGO B blocks are designed to connect seamlessly with popular non-magnetic building systems, including DUPLO® and LEGO®. This means you can merge your Smartek creations with your existing bricks, opening the door to even bigger, bolder builds.

Whether you’re stacking, bridging, or building in every direction, Smartek’s patented Dutch design combines the tactile satisfaction of magnets with the boundless creativity of open-ended play.
