Negative ions, ozone, and germanium work together to balance the ions inside and outside the skin, helping to restore your skin's natural beauty. This is a cordless beauty roller that can be used anytime, anywhere, after applying your usual lotion. The box is worn, but I've only used it once or twice. The included adapter was yellowed, so I will include a different one. Please refrain from purchasing if you are sensitive to used items. Original price: ¥23,940
