WAHL, an American clipper top manufacturer with a 100-year history. This product is a Japanese specification 100V 50Hz model with a PSE mark. 50Hz is for the Eastern Japan region: Chubu Electric Power, Tokyo Electric Power, Tohoku Electric Power, and Hokkaido Electric Power. *Please note that Shizuoka and Niigata prefectures have mixed 50Hz/60Hz areas. If you want to do fade cuts and skin fades like those seen in street and hip-hop styles, I think a clipper from a genuine American manufacturer is the best choice. ◆This product uses a magnetic motor, so you may hear a clicking sound when you turn it on, but this is normal, so please rest assured. I have cleaned it as much as possible, but I am an amateur, so I cannot do a thorough disassembly and cleaning. Please refrain from purchasing if you are concerned about this. Body area: Other Color: White Type: Other Waterproof: No waterproof function Power supply: AC Weight: 500g to less than 1000g
