The Gillette ProShield blade refills 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 five antifriction blades gives you a shave you can barely feel and the Precision Trimmer on the back is perfect for hard-to-reach places and styling facial hair. Our thinnest, finest blades (first four blades) are designed for less tug and pull (vs. Sensor3). Each refill can last up to one month, keeping your razor and your shaves at their best. Gillette Fusion5 ProShield, these blade refills can fit all Gillette 5-bladed razor handles.
