Purchased from Rakuten online shopping about two years ago (various manufacturers offer similar products, but this one is priced around 2800 yen). I was curious about how it worked, so I tested it once on the back of my hand, but then put it away. Operation confirmed. Will be shipped via Yu-packet. Thank you very much. ****************************** Please understand that this is a used item stored at home before purchasing. Please refrain from price negotiations.
