I love Tamas and have been collecting them, but I'm selling them because I have too many. I've used these a few times. I have disinfected them with alcohol, but please purchase only if you are not concerned. There is some dirt on the central unevenness. Please be aware of this beforehand. Size: 10 x 15mm Catch: Brass * Resin catch, bag, and box are not included. Purchase price: ¥17,600
