The Gillette Fusion5 men's razor blade refills feature 5 antifriction blades so you can get 5 blade closeness at an affordable price. These blade refills for men are spaced closely together for incredible comfort lasting you up to 20 shaves per blade refill. The precision trimmer on the back of the razor makes getting your hard to reach places easier and is great for styling your facial hair just the way you want it. Soft microfins gently stretch and smooth your skin to prepare the hairs for a close shave from our thinnest blades (first 4 blades) while the lubrastrip helps the blades glide over your skin more easily. A Lubrastrip is a thin strip that sits at the top of the razor, releasing lubricants while you shave, to produce a great glide. When you are no longer getting an optimal shave, the Lubrastrip fades to white, indicating that it might be time to change the blade. All Gillette 5-blade razor handles will fit these Fusion5 razor blades (excluding GilletteLabs).
