Since accuracy is an important criterion for hair clippers, the ER-GP21 features a precise cutting-length setting that can be conveniently controlled via a slider. The compact device is very quiet and skin-friendly. The slim body makes the hair clipper easy to use and ensures safe and precise control even by small hands. A rubberised surface on the underside provides extra grip and prevents slipping. Thanks to the waterproof housing, the device can be easily and hygienically cleaned.
