Looking for baby clothing at Muji Japan as suggested by Kimiko, I came accross this o! surprising Lego & Muji love affair. I don’t understand Japanese so I did not make lots of sense with the text, but it seems pretty neat:
You combine Lego bricks to craft materials to fluidly assemble creatures, people, or even Christmas cards. A great way to expand the way kids work with traditional Lego blocks, integrating unlimited paper craft creations, meaning unlimited imagination.
As soon as this becomes available here, I’ll get myself a kit!!
