Thank you for viewing this piece. This work is a [5-hook] key case. The Tochigi leather has been carefully painted with persimmon tannin using a brush, creating a warm, wood-grain-like texture. There are no two alike in the world, which is also a charm unique to hand-dyeing. Persimmon tannin dyeing appears in different colors depending on the light, showing various expressions. If you want to "own a one-of-a-kind item," why not take this opportunity? All stitching is done by hand, and the main body is made firmly using 3mm leather. It would also be a great gift for someone special! [Size] Height: Approximately 110mm Width: Approximately 60mm [Persimmon Tannin Dyeing] Persimmon tannin is a natural dye made by squeezing unripe persimmons and fermenting and aging them. The history of persimmon tannin dyeing is long, a traditional dyeing technique passed down from the excellent predecessors of the Heian period. From the "Kaki-koromo" (persimmon robe) worn by samurai and yamabushi (mountain ascetics) in the Heian period, to its "high fastness (the degree to which color fades or transfers due to washing or friction, etc.) and less worry about color transfer or fading," and "insect repellent, deodorant, and waterproof effects," it has been used in everything from fishing nets, oiled paper umbrellas, and wood paints. Furthermore, the pigment component, persimmon tannin, undergoes condensation polymerization over time, so the color becomes stronger and changes the more it is used and the older it gets. Please nurture it as "character." ※Please note※ Persimmon tannin has various effects, but it does not mean that it does not require maintenance. ●Because natural leather is used, there may be some scratches or wrinkles, but there is no problem with use. Please enjoy it as a sign of life. ●The color may differ slightly from the actual product depending on your PC environment. ●We pay close attention, but there may be scratches or scuffs remaining during production. ●This is a handmade item made as a hobby, so there may be some individual differences, but we ask for your understanding.
