Gillette Mach3 Turbo men’s razor blade refills features 3 blades for glide and comfort. With sharper, turbo cutting blades (first 2 blades), it delivers a closer shave, without all the irritation. This razor blade feels better than a new disposable, even on the 10th shave. The long-lasting Comfort Gel Bar provides an incredible glide. Mach3 features 2x more Skin Guard fins for a smooth shave (vs Gillette Blue3 disposable). These Mach3 Turbo blade refills can be used with any Mach3 razor.
