50 Derby Extra Double Edge Razor Blades Stainless Steel

I've only tried a couple of different double-edged razor blades so I'm not an expert, but I read several positive reviews of the Derby blades before buying. Good quality blades which come individually wrapped in packs of five, with slots for disposing of used blades in the package. These are very forgiving blades that allow for multiple passes over the face (or whatever area you're shaving, I assume -- I can only vouch for the face). Not the sharpest, but they hold up well to my very coarse beard. Would definitely purchase again!
