Retail price: 25,000 yen This item is listed as a men's long wallet, but it's thin, compact, and lightweight, making it easy to use even for a woman like me. It doesn't take up much space in a bag, so it's also recommended for women. Made from a single piece of leather and constructed with only bolts and nuts, similar to those used in the Tokyo Skytree. I've used it for several years, and as you can see in the photos, there are some minor scratches, but the card slots and the bolts and nuts are still in good condition without any looseness or wear. Despite its unique shape, it never opened on its own inside my bag. I saw someone else using it, and the way it opens and wraps around when in use is quite elegant, so I bought one myself. I loved it, but I received a wallet from a friend, so I'm selling this one.
