The leather used is high-quality Himeji cowhide, which allows you to enjoy the aging process, and the entire piece will gradually change to an amber color the more you use it. We hope you enjoy nurturing it. It was handmade with all hand-sewn construction. The careful stitching results in beautiful stitches. ◆ Wallet Size Height: Approximately 9cm, Width: 14.5cm, Thickness: 2cm ◆ Leather Thickness 1.7mm, a slightly stiff and durable leather. ◆ Leather Color Natural (tanned color) ◆ Finish Carefully finished by hand, especially the bonded areas of the leather (edges). We repeatedly applied and sanded Italian Fenice water-based edge finish until it was smooth. Known for being used in high-end leather goods, it is characterized by its strong coverage, resulting in a finish where the bonded areas are invisible. ◆ Closure We use gold spring snaps instead of jumper snaps because they are too stiff. ◆ Structure It has a simple structure with one coin purse, four card slots, and one bill compartment! ◆ Zipper We use YKK Excella zippers with a brown tape and gold hardware. Each element is carefully polished, pursuing beauty and a smooth feel, resulting in a luxurious zipper. ◆ Thread The hand-sewing thread is Vinymo MBT in gold. ◆ Notes Due to the natural materials, there may be some scratches or stains depending on the part of the leather used. Please understand that this is handmade.
