This is a handmade, hand-stitched business card holder/card case made with navy vegetable-tanned Tochigi 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 credit cards. Please use it to separate frequently used cards from less frequently used ones, your own business cards, and those you've received. It is hand-stitched with navy Vinymo thread, and the edges are finished with Tokonole. Both the interior and exterior use luxurious, domestically-produced Tochigi leather. The aging process will progress as you use it, and it will develop a unique character. It was made carefully using good quality leather. Please take care of it from time to time, enjoy the aging process, and I hope you will use it for a long time. ※This item is also listed on other sites.
