The Feather MR3 Blades are triple blade cartridge replacement blades with a semicircular guard. It provides the closest shave out of the 3 F-system blades (F3, MR3, F2Neo). This also means it gives the most aggressive shave out of the three. Blades are sharp, but some protection is provided by the semi-circular guard. Each cartridge features a metal roller for a close and comfortable shave. Made in Japan.
