This business card holder realizes the traditional Japanese technique of "Fukkin Machi" (accordion gusset) by improving the pattern, achieving excellent storage capacity and ease of use. It features four pockets and can hold approximately 55 business cards in total. [What is Fukkin Machi?] Fukkin Machi is a unique traditional Japanese technique characterized by its ability to store many cards in a small space and allow for smooth retrieval. A typical gusset folds inward ("valley fold"), which can cause snagging when inserting or removing cards. Fukkin Machi, on the other hand, folds outward ("mountain fold"), creating a structure that makes it easy to insert and remove cards. However, it is a highly difficult technique to produce, with only a limited number of skilled artisans possessing the expertise, making it a highly valued and rare technique.
