Replacement Cartridge Blades are a quick and convenient way to aid the shaving flow as it were. When one blade becomes dull or less sharp then simply replace the cartridge then carry on for a great, smooth shave with as little fuss as possible.
It's quick and it's easy.
The most popular 3 blade system is The Mach3 from Gillette. The four blade choice would be Wilkinson Sword's Quattro Titanium Precision, whilst the 5 blade choice of many is the Fusion, from Gillette.
You need to be 18 years old to purchase Razor Blades.
Please dispose of used blades responsibly.
