Nobu used to be obsessed by Lego. This lasted for so many years, age 3-10. As a baby, he did Duplo, then he graduated to regular Lego. He loved the sets, and he played Lego video games, Batman, Star Wars, etc. It is quite a franchise.
I like the concept, even if I don’t like the Lego marketing. I thought, why not make bricks in glass? It works! These bricks are the size of a regular red brick.
