Gillette Fusion ProGlide Power Shaving System, with 8 Refill Blades. The thinnest, finest Gillette blades (the first to fourth blades, the same as the ProShield). Pulls less on the hair (as in the merger in comparison). Specially designed to reduce precision knife pressure per meter for a comfortable shave (compared to Mach3). Precision trimmer on the back for accurate machining of hard to reach areas (nose and whiskers). The Microkam helps guide stubble to the blades. With a Refill Blade can shave a month. Suitable for every Fusion shaving system.
