Building blocksWhatever Inc.
Tsumishi is a completely new building-block-type toy that is designed around a new assembly mechanism. Each block is made of stacked paper, which can be interlocked and held together at the sides, rather than just piling them on top of each other. As a result, Tsumishi allows you to combine and create structures and shapes that are seemingly impossible with conventional building blocks. People of all ages can use the building blocks and their imagination to create unique objects.
