Gillette Mach3 men’s blade refill delivers a close shave, without all the redness while feeling better after the 10th shave than a new disposable does on the first (vs. BlueII Plus Disposable). It features 3 DuraComfort blades for long-lasting comfort. A lubrication strip glides to help protect your skin from redness, while an advanced skin guard helps stretch your skin, and prepares your hair to be cut. Mach3 blade refills fit all Mach3 razors.
