I've only had it for two weeks. I've only used it once. I didn't feel any effect, so I'm putting it up for sale. It's clean since I've only used it once. It will be wrapped in cushioning and sent in a bag because it will be bulky in the box. If you want the box, I can include it for an additional 1000 yen. It's a genuine product purchased from amepla. No price reductions. Thank you very much.
