Handmade billfold, designed to naturally open when unzipped. This is "#Leather Goods Workshop," active in Nikaho City, Akita Prefecture for 50 years. Thank you for viewing. This is an original product of our workshop. Unlike mass-produced items, the leather used is sturdy and of high quality... It's made with tannin-tanned leather, also known as "combined tanning," and is designed to maintain its shape and prevent the bottom from peeling even after years of use. bw08
