The Philips QP2724/22 OneBlade Face trims, edges, and shaves any length of hair. The OneBlade has a revolutionary new technology designed for facial styling and body grooming. Its dual protection system makes shaving easier and comfortable. Trim your beard with 5-in-1 adjustable comb in any direction. You are able to create precise edges with the dual-sided blade. You can shave in either direction so you can see every hair that you're cutting. OneBlade is fully waterproof, so it is easy to clean: just rinse it under the tap. OneBlade trimmers do not shave as close as a traditional blade, so your skin stays comfortable. Go against the grain and shave off any length of hair easily on your face.
