Gillette Mach3 blades feature 3 DuraComfort blades for enhanced comfort and an easier shave, without all the redness. The blades are independently mounted on spring fingers. The responsive blade suspension keeps the blades in close contact with your skin, and the pressure-adjusting pivot adapts to contours of your face for an easier*, comfortable shave. Offering both the convenience and longevity that only comes with refillable blades, this razor blades include 5 soft, flexible Microfins to bring you a close, comfortable shave, while the Indicator Lubrication Strip helps with better glide and fades to white when you are no longer getting an optimal shave from your razor blades.
