Perma-Sharp Super Blades are a high quality blade made in Russia by Procter and Gamble. These stainless steel blades are coated with PTFE (a.k.a. Teflon) to ensure smooth shaves and long lasting blades. They are a favorite of wet shaving aficionados for being both sharp and forgiving. They are prized for holding an edge longer than most blades. Pack contains 5 blades, and each blade is individually wrapped to assure safety, sterility and long shelf life. Blades fit all traditional double edge razors. To avoid rapidly dulling the blade's sharp edge, remember to always rinse it after use, never wipe it. $1.80
