The Gillette Pro Glide men's razor with Flex Ball technology responds to your contours giving you uncompromising closeness and comfort. The handle's Flex Ball technology responds to contours and the blade refill features 5 antifriction blades for a shave you can barely feel. The blades are spaced closely together for incredible comfort with a precision trimmer on the back for hard to reach places and for styling your facial hair just the way you want it. The enhanced lubrastrip (vs. Fusion5) has more lubricants for comfort and glide. This enhanced lubra-strip also fades when you are no longer getting an optimal shave. Soft micro-fins gently stretch and smooth your skin to prepare hairs for a close shave while a micro-comb helps guide your hair for a close shave from our thinnest blades. The Pro Glide razor for men features our sharpest blades (first 4 blades) which help get virtually every hair effortlessly. One razor blade refill lasts up to one month of shaves. All Pro Glide blade refills can fit all Gillette 5 blade razor handles (excluding Gillette Labs).
