Thank you for viewing our products. This is a cowhide book cover for a single-volume book (hardcover) size. ＜Leather＞ The surface uses domestic cow tan leather. Tan leather is an abbreviation for tannin-tanned leather for wax dyeing. Tan leather is also a type of nubuck leather, which is nubuck leather that has been degreased and made easy to dye, making it the perfect leather for this product, which is dyed by wiping. The inside uses cow chrome leather, prioritizing usability. ＜Design＞ Our workshop designs with the concept of one-of-a-kind leather goods. We arranged the stamps on the tan leather and dyed it in-house using a wiping dyeing technique. Wiping dyeing is a technique in which, after dyeing once with the base color, the outlines of the stamps are blurred to a certain extent with a brush like a teru teru bozu (a traditional Japanese doll made of white paper or cloth, hung outside to pray for good weather). By doing so, it gives an antique feel and a warm impression. The stamps are arranged not only for their design but also considering the feel when held. In addition to the stamp arrangement and dyeing, the greatest feature that other material book covers do not have is that the more you use it, the more the luster increases with age, making it even easier to use. Color: Multicolor (blue系) Sleeve leather: Black Motif: Floral pattern Size: Width 31cm x Height 21.1cm (when spread out) ※Occasionally, it may be sold at the physical store at the same time, so if you do not want a remake, please contact us to confirm the stock before purchasing. ※If it exceeds 600 pages, it may not be possible to cover it. Please contact us and we will check if it can be attached. ※Since we dye natural leather in-house, there may be scratches unique to leather and color unevenness due to tampon. Also, it may penetrate the back and look like a stain. These are characteristics of the technique and cannot be completely prevented. ※If you have any questions other than the above, please feel free to contact us. ※As a factory-based workshop, we do not offer services such as gift wrapping.
