For an incredible, close shave use these Mach3 Razor Blades from Gillette. Mach3 razor blades feature stronger than steel blades that stay sharper for longer so you can get a smooth, close shave again and again. A lubrication strip ensures that the blade glides easily across the skin, helping to protect it from redness and irritation. The razor blades also feature a microfine skin guard, which stretches the skin, prepares hair to be cut and prevents unsightly and annoying shaving rash. The Mach3 razor is engineered to last 15 comfortable shave. This refill pack contains 8 Mach3 cartridges (enough to last you 120 shaves).
