I'm selling a hot eye mask I purchased on Amazon. I bought it for around 6000 yen for an eye massage and used it a few times. It doesn't have the box or instruction manual. I only used it in the winter, so it's not dirty. It's in good condition. I believe it was this product: https://www.amazon.co.jp/%E3%83%9B%E3%83%83%E3%83%88%E3%82%A2%E3%82%A4%E3%83%9E%E3%82%B9%E3%82%AF-360%C2%B0%E3%82%A8%E3%82%A2%E3%83%90%E3%83%83%E3%82%B0-%E6%8C%AF%E5%8B%95%C3%97%E7%A9%BA%E6%B0%97%E5%9C%A7%C3%97%E3%82%B0%E3%83%A9%E3%83%95%E3%82%A7%E3%83%B3%E5%8A%A0%E7%86%B1-Bluetooth%E9%9F%B3%E6%A5%BD-%E8%87%AA%E5%8B%95%E3%82%AA%E3%83%95%E3%82%BF%E3%82%A4%E3%83%9E%E3%83%BC/dp/B0DCG7DC63
