MACH3-Gillette Replacment Cartridges, 16 Cartridges (2Pack)

* 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. * Patented DLCTM comfort edges ... 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.
