This is a handmade, hand-stitched business card holder/card case made with yellow Tochigi leather (vegetable-tanned leather) for the exterior and natural Tochigi leather for the interior. It has pockets in the front, back, and cover that can hold 1-2 cards each, and a large pocket in the middle that can hold 20-30 business cards or a dozen or so cards. Please use it to separate frequently used cards from less frequently used ones, your own business cards, and cards you've received. It is hand-stitched with dark green Vinymo thread, and the edges are finished with Tokonole. Both the exterior and interior use luxurious, domestically-produced Tochigi leather. The aging process will progress as you use it, and it will develop character. It was made carefully using good quality leather. Please take care of it from time to time and enjoy the aging process, and I hope you will use it for a long time. *This item is also listed on other sites.
