I bought this used for about 25,000 yen from a secondhand shop about three years ago, and I used it two or three times before putting it away. The exterior appears to be in very good condition, and I've confirmed conductivity. You should be able to find more information by searching for the name, so please do your own research for details. I will answer some questions regarding shipping, etc. No returns or refunds. I am generally not accepting price negotiations.
