Our gillette mach 3 razor blades give you the reliable gillette shave with comfort and precision. Each razor blade refill is engineered to last up to 15 comfortable shaves, so you can get the most of every shave. Our thinnest razor blades (first two blades) are stronger than steel, so they stay sharper longer (vs. Sensor3). Along with durability, the lubrication strip glides for a smooth shave while soft microfins gently stretch and smooth skin, preparing hairs to be cut for the optimal shaving experience.
