"SAITEKI" DESIGN = Ideal Shapes, Ideal Designes

ace. products are created under the product concept of "ideal shapes and ideal designs." These shapes and designs have a pleasing effect on people,reflecting the Japanese sense of beauty much like the pleasure felt when listening to the Japanese koto (harp). Creating these designs is like formulating silver ratios in jewelry, as it requires carefully balancing a variety of factors, such as dimensions, pocket positions,and component relationships. The designs we create are inspired by Japan's unique love of nature, formative art, and functional beauty.

The origin is "帯 obi" of the kimono

Obi is a fashionable way to dress your back, which you cannot see, but it is seen by otheres. Dressing your back…that's backpack. We take a hint from the square shape of the "odaiko", one of the ways to tie an obi.
