Hand-stitched genuine leather business card/card holder for M5 system notebooks. The main body uses Tochigi Leather in dark green, and the pockets use Tochigi Leather in red, hand-stitched with dark green Vinymo thread. The edges are burnished with Tokonole. To avoid blocking the binding holes even when cards or business cards are inserted, the width is about 8mm wider than the M5 refill. It shouldn't stick out from the notebook cover, but please check before purchasing. *Also listed on other sites. If it sells quickly there, we will cancel the order. Thank you for your understanding.
