Germanium Slim Roller (99.999% pure semiconductor) - When germanium, a rare metalloid semiconductor, comes into contact with the skin, it normalizes the body's electrical potential. Just roll the roller and you'll have beautiful skin! I bought this several years ago for nearly 20,000 yen, but it seems to be selling for around 15,000 yen now. I gave it to my mother as a gift, but she didn't use it much, so it came back to me. I also bought a different beauty device, so I'm selling this one. I purchased it over 5 years ago, but I believe the effect is semi-permanent. Care... Lift-up Area... Face
