I purchased this about a year ago from a shop that sells vintage European clothing. At the time, it was 11g and cost 1000 yen per gram, so I paid 11,000 yen. It's made of silver with a purity of 95% or higher, which is soft and resistant to discoloration, and it's also easy to care for, which is a nice feature. I'm selling it because I haven't had many opportunities to use it.
