Size: 136mm x 121mm I have a bulk purchase, but I'm selling it because I no longer have the opportunity to use it. There are 2 sheets x 2 sets, for a total of 4 sheets. I have opened it once, but it is a new, unused item. Although it is a beautiful item, it has been stored by a private individual, so please refrain from purchasing if you are nervous about this. Immediate purchase is welcome ◎
