Muji's A5 size notebooks will also fit. ＜Leather＞ The exterior uses domestic vegetable-tanned white leather (cowhide). After arranging the stamps, we dyed it in-house. The interior uses soft chrome leather. ＜Design＞ Our workshop designs with the concept of one-of-a-kind leather goods. We arranged stamps on the white leather and dyed it in-house using a wiping dye technique. The stamps are arranged not only for their design but also considering the feel when held. The wiping dye technique is used for dyeing, and the contours of the stamps are blurred to give a warm impression.
