The Gillette Fusion5 razor for men features a premium, Signature Edition razor handle and 5 anti-friction blades for a shave you barely feel. Along with durability, these Gillette razors feature a lubrication strip that glides to help protect your skin from redness, while soft micro fins gently stretch and smooth skin, preparing hairs to be cut for the optimal shaving experience. 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. One razor blade refill equals up to one month of shaves. Not sure if these blades will fit your existing handle? This Fusion5 handle conveniently fits all Gillette 5-blade razor refills. For best results, use with your favorite Gillette shave gel, cream or foam.
