A razor blade refill for razors corresponds to up to one month of shaving. Gillette Fusion5 razor blades fit all Fusion razors & Fusion Power electric razors. 

The Gillette Fusion5 ProGlide razor blade has 5 anti-friction blades and a precision trimmer on the back for hard-to-reach areas. Gillette Proglide has an improved Lubrastrip for more glide compared to other razors in the Fusion5 series.

The lubrication strip fades when you no longer get an optimal shave.
