Gillette Mach 3 Refills 4 Cartridges

3 Blades...specially positioned to extend gradually closer to your beard, to shave you progressively closer in a single stroke. So close there is less need to reshave, which means less irritation.

DLC anti-friction edges...each blade has a DLC anti-friction edge, so Mach 3 glides effortlessly and comfortably across your face. The Mach 3 Indicator lubricating strip has a blue stripe that fades away when you are no longer getting the optimal Mach 3 shaving experience.
