Shark Double Edge Safety Razor Blades Pack x5
REPLACING: To replace the blades in your safety razor, simply unscrew the handle from the razor head by twisting it counter clockwise. Then unclip the top plate and remove the old blade. Drop the new blade into position, replace the top plate and screw the handle back up. It's as simple as that.
RECYCLE: Why not collect your old blades in a metal tin or jar to then recycle them all once full? Make sure to keep them out of reach of children though.
If your safety razor is beginning to catch a little on both sides (remember there are two sides on a safety razor), then its probably time to replace the blade. This might be as often as every few days or every few weeks depending on how much you use it and how thick your hair is.
