Gillette Fusion ProGlide men's razor with Flex Ball technology. Follows the contours of the face, removing almost every hair. 5 precision blades for incredible comfort. With Gillette's thinnest blades (the first 4 are the same as the ProShield), the ProGlide razor moves with less friction than the Fusion. The back of this razor features a precision trimmer that helps you create a defined edge in hard-to-reach areas, including your sideburns and upper lip. One replaceable cassette is enough for one month of shaving. This Fusion ProGlide razor fits any Fusion razor cartridge.
