Building blocks tumi-isi
Polyhedral building blocks for children and adults.
Objects to develop a sense of balance and creativity. The irregularly shaped polyhedrons and moderate grip provide a unique stacking experience.
To make them fun to display as well, each piece is individually beveled to a different size and shape by our craftsmen so that they can be arranged as a single object.
In order to maintain the highest quality, everything from processing, painting, assembly, to inspection is "all made in Japan" in Higashiyoshino village, Nara prefecture.
《How to care for it》.
Moisturize it regularly to prolong its service life. (Remove dirt with a wrung out rag, apply rice oil or olive oil, and wipe off.)
Maintenance can be performed for a fee. If you wish to have it resharpened → repainted, please contact us from the "tumi-isi" official website.

Each piece differs in grain, weight, and shape because it is made of natural solid wood and processed by hand. In particular, the shape is cut at random, so there are individual differences. The coloring is also done by hand, so there may be unevenness in the paint, but it will become a nice texture as it is used.
