Gillette Mach3 men's razor blade refills deliver a close shave, without all the redness, while feeling like the first even after the tenth shave than a disposable does on the first*. Each razor blade refill features three DuraComfort blades for long-lasting comfort. Gel strip glides to help protect your skin from redness, while an upgraded skin guard helps stretch your skin in order to prepare your hair to be cut. These Mach3 blade refills can be used with any Mach3 razor. * versus Gillette Blue II
