I purchased this along with MEDULLA shampoo, etc., but I'm selling it because I haven't had a chance to use it. Since it's new and unopened, I haven't been able to confirm its operation. Product Name: MEDULLA SONIC-SHINE PRO 　　　　MEDULLA Sonic Shine Pro 　　　　Ultrasonic Hair Care Treatment Device Size: 36mm x 41mm x 278mm Although unopened, the surface vinyl caught when removing it from the box, and there is a small hole in the vinyl (see photo 3). It is new and unused, but it has been stored at home, so please understand this before purchasing. #MEDULLA #MEDULLA #HairCare
