I purchased this from the official website two years ago, but never had a chance to use it and forgot I even bought it. I haven't used it at all. It's been stored in a rarely-opened shelf in the bathroom. The retail price was 17,600 yen. I'm selling it at a bargain price because I don't have the manual or box. I will pack it with cushioning material and secure it in a cardboard box to prevent movement during shipping. Please understand that I am an amateur at storage and packing. Instant purchase and price negotiations are both welcome!
