This is Gillette's thinnest blade so far for use in battery assisted razors. It has a low resistance coating for a smoothe glide and ultimate comfort. The back of the cartridge features a truly innovative Precision Trimmer. The Precision Trimmer is a single blade built into the back of the cartridge. To use the trimmer, you turn the razor over. In this position the pivot feature is locked, giving consumers control and allowing them to better align and manoeuvre the blade. The locked pivot allows consumers to easily shave tricky places like sideburns and under the nose. Fits Gillette Fusion ProGlide Power Razor Contains: 4 Fusion ProGlide Power razor blades
