5 single specialty blade refills = 1 cartridge.
Simply load an entire cartridge inside the handle.
The cartridge inside is activated by clicking the star forward and your next blade will appear. The display window shows you what blade your using.
Every 6 days/shaves you should click to a new blade.
Once the cartridge hits the 5th blade you will have only 6 more shaves before inserting an entire new cartridge replacement.
The specialty wire wrapped blade design makes it a challenge to cut or nick your skin. Finally stress free shaving with no irritation.
