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 experience. The three DuraComfort blades feature Open Blade Architecture for easy rinsing to keep your razor clean and performing its best. Not sure if these blades will fit your existing handle? All of our Mach 3 razor blades fit all Mach 3 razor handles.
