These beautiful wooden building blocks (Tsumiki in Japanese) are designed by Toshiaki Yamada and made in the Ore Mountains in Saxony. They have discrete but effective notches to couple the blocks to each other. This modification combined with their shapes and arches, enable them to go beyond stacking blocks, since they can create sculptures seeming to defy gravity, without any fasteners or connecting pieces.
The building blocks comes in a wooden box with a sliding lid.
