The Gillette Mach3 Razor Blades are engineered for a reliably close and comfortable shave. Each cartridge features three precision-ground blades designed to cut hair cleanly. These replacement parts include a MicroGuard system, which helps guide the blades for a smooth pass and a close finish. The integrated lubricating strip activates with water to deliver Gillette's Optimal Glide Effect, minimizing friction and reducing skin irritation during shaving. Designed for durability, each blade is intended to provide up to 15 comfortable shaves, ensuring consistent performance over time.
