The Gillette ProGlide Shield men\'s razor adds lubrication before and after the blades, giving you a comfortable, smooth shave. The FlexBall technology responds to contours and gets virtually every hair and the five antifriction blades are our thinnest, finest blades (first four blades) for less tug and pull (vs. Sensor3). The Gillette ProGlide Shield blade refills also provide lubrication before and after the blades to help shield skin from irritation while you shave. Giving you a close shave, the microfins gently stretch and smooth skin while the microcomb guides your hair to the blade. The Precision Trimmer on the back is perfect for hard-to-reach places and styling facial hair. Each refill can last up to one month, keeping your razor and your shaves at their best. Concerned your Gillette handle won\'t fit? All ProGlide Shield refills fit all Gillette 5-blade razor handles (except GilletteLabs). Also, each refill lasts up to a month of shaves, giving you the ability to customize your shave and get the most out of every blade. Formerly known as Gillette Fusion5 ProShield.
