This is an electric device for heel care♪ It's used to smooth rough skin with a circular plate and to smooth the edges of the smoothed skin with a conical plate. I ordered it with a catalog gift, but I'm selling it because it's been sitting unused. ✿ Specifications Length x Width x Height: 140 x 55 x H60mm Material: Main body/mounting parts: ABS resin, Switch: Rubber Set contents: Circular plate #150, Conical plate #150 Weight: Main body approx. 105g Power supply: 2 AAA batteries (sold separately)
