Gillette Mach 3 Cartridges are a revolutionary new triple-blade shaving system for the closest shave ever in fewer strokes - with less irritation.
Gillette Mach3 Blades has blades that are 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 re-shave, which means less irritation. Each blade has a patented DLC comfort edge, so Mach3 glides effortlessly across your face. And Mach3 has an advanced Indicator lubricating strip with a blue stripe that fades away when you are no longer getting the optimal Mach3 shaving experience.
