I cannot think of a better combination for a creative play set than Muji and Lego. The Muji + Lego sets, including Lego bricks and paper sheets, are perfect to build anything using your imagination and a punching tool. The punching tool that makes wholes the right size to connect the paper with the Lego bricks is not included in the set, but it can be purchased separately. I love the selection of animals you can build. The sets have a theme so you have material that is more suitable for certain types of constructions, like travel vehicles or animals, but your kids’ imagination can go beyond the suggested ideas and make whatever they want with it.
