The ES-RF31 offers a thorough and gentle wet or dry shave. Its 4-blade shaving head with super-sharp 30-degree blades ensures an exceptionally smooth shave. Thanks to the curved shaving foil and the super-flexible shaving head, the razor adapts perfectly to the contours of the face, ensuring that the beard hairs are cut very close to the skin. The extra-thin shaving foil for fine detailing removes even particularly short and close-lying beard hairs for a perfect finish. The durable lithium-ion battery of the ES-RF31 charges quickly and lasts for several weeks with daily shaving.
