This is a handmade goshuin-cho (temple stamp book) cover. Interfacing is applied to the outer fabric. A 12x18 cm goshuin-cho fits with room to spare. There is no fastener, but the flap is large, so you can securely store your goshuin. It's easy to take in and out. It will be shipped via standard mail, but if you purchase multiple items, it will be shipped via Mercari delivery. I make each item with care, but it is handmade by an amateur. Please forgive any slight imperfections. Also, please understand that there may be some fabric debris or slight snags that are original to the fabric.
