I purchased this a few years ago from someone who used to work in an esthetic salon (for just under 100,000 yen; apparently it originally cost over 300,000 yen). I used it a few times, but then I bought a different device and put this one away. It's quite large, so it takes up some space. It's easy to use; just spray Swartz and shine the light on it for about 10 minutes. I've confirmed that it powers on. When I tried it once, it definitely made my skin firmer. It's also supposed to be good for hair growth. How about adding it as an option in your esthetic salon? *Please refer to the photos for usage instructions. *No stand included (body only). I purchased it several years ago, so there is no warranty.
