The Gillette Mach3 razor combines Gillettes 3 Blade Shaving Technology with Anti-Friction blades that offers a comfortable shave, along with the longevity that comes only with exchangeable blades. Its comfort guard includes 5 microfins to bring 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.
