♪ Thank you for viewing. Hand-stitched cowhide system notebook, mini 5-hole. This is a one-of-a-kind item, handmade from cutting the leather to sewing. It is sewn with a cross stitch using a needle, so even if the thread breaks, it will not unravel, allowing you to use it for a long time. ● Product Description Material: Cowhide, 1.5mm thick Color: Black Binder hardware (Ring inner diameter: 15mm, Ring outer diameter: 19mm) Size: 12.5cm x 8.5cm Since it is also sold in stores, please check the stock in the comments before purchasing.
