The Gillette Mach3 Shaving Cartridge 3 Blades continues its legacy of close shaves. Its 3-blade technology offers a comfortable shave, along with the longevity that comes only with exchangeable blades. Its Comfort Guard includes 5 microfine to give you a close, comfortable shave, while the indicator lubrication strip fades to white to show when you are no longer getting an optimal shave from your razor blade.
