Handmade genuine leather book cover [For paperback books, compatible with Hayakawa Bunko: Wrap-around type]. This is a genuine leather book cover that enhances your reading enjoyment and protects your precious books. It also makes a great gift for book lovers. [About the item for sale] (Individual description) Leather used: High-quality cowhide (vegetable-tanned), firm. Color: Black Due to the natural aging process unique to vegetable-tanned leather, you can enjoy the changes in gloss and color as you use it. The flesh side (back side) has a short-pile suede-like texture. It feels soft and gentle to the touch. To preserve the texture of the leather, no adhesives or treatments have been applied. The flesh side of the outer band has been treated to be firm and crisp, allowing the flap (tab) to slide through smoothly. [About the structure] (Common description) - The flap wraps around the book and can be inserted into the outer band. This protects your precious books from scratches and dirt. - The inner thick band secures the book. You can read without inserting the flap, making it convenient for quick reading on the go or during commutes. - The flap can also be used as a simple bookmark. This is useful when you need to step away from your book briefly or want to mark your page. - The adjustable structure accommodates paperback books of different thicknesses. The photos show books with thicknesses of approximately 11-30mm. Thicker books can also be accommodated, but if they are too thick, the back cover may be visible from the part where the flap narrows, or the flap may not reach the outer band. Even so, the flap is wide enough to accommodate books of considerable thickness. - The sides are finished cleanly without visible stitching. The rounded edges that come into contact with your fingers provide a pleasant feel. Size: Approx. 17.0cm x 35.6cm (when unfolded) Leather: Cowhide (vegetable-tanned) (The item for sale is only the book cover.) Please note that there may be minor imperfections such as uneven stitching or marks from tools. Also, the leather itself may have minor scratches or color variations from its natural state. Please understand these as the natural characteristics of genuine leather. I also have other leather items for sale. I can offer a slight discount for combined purchases, so please comment if you are interested.
