Never used. The following is quoted from the vifj online store: A super lightweight, simple wallet, only 3mm thick and weighing 40g. With a size that matches the size of a Japanese 10,000 yen bill, it has an innovative design with six cards arranged vertically in a row. It also has a shallow pocket for receipts, allowing for beautiful sorting. The wide, horizontal coin purse has more storage capacity than it looks, and is easy to take out and store. The overall simple and compact design doesn't take up space even when placed in a trendy mini bag, and it doesn't bulge much even when placed in an inside suit pocket.
