This is a Nambu-nuri postcard holder. I've had it at home for many years, but it's unused. I've touched it with my bare hands several times. I believe it's from the Showa era. Size (inside the holder): Width: Approximately 14cm Height: Approximately 20cm Depth: Approximately 2.8cm There is a scratch on the corner of the bottom of the holder. Please check the fourth photo. I think it would also be wonderful as an interior decoration for a Japanese-style room. I don't have a chance to use it, so I would be happy if someone would use it.
