Make sure you have plenty of Gillette Fusion Manual Refill Cartridges on hand. Gillette Fusion is a great way to shave for any man, whether he's clean-shaven or has facial hair. On the front of the shaving cartridge, Gillette Fusion has a 5-blade Shaving Surface technology. The blades are 30% closer together than those in the Mach3 razor family. This creates a shaving surface that evenly distributes shaving force across the blades, as well as a Lubrastrip that fades from green to white to indicate when shave conditions have improved. The Precision Trimmer blade is a single blade that is built into the cartridge's back. That was a fantastic shave.
