Gillette Mach3 men's razor blade refills gives you the reliable Gillette shave with comfort and precision. Our thinnest blades (first two blades) are stronger than steel, so they stay sharper longer (vs. Sensor3). Each blade refill is engineered to last up to 15 comfortable shaves, so you can get the most of every shave. 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. The three DuraComfort blades feature Open Blade Architecture for easy rinsing to keep your razor clean and performing its best. Each ergonomic MACH3 handle fits all MACH3 blade refills.
