I purchased these blades at a CVS pharmacy. They were inexpensive for a pack of 10 stainless steel blades, so I thought I'd give them a whirl. What I found left me quite disappointed. To begin with, when I opened the package and removed the first blade, I found rust on the surface and along the edge. The next two blades were also rusted, though not as much. It wasn't until the fourth blade that I found no rust. I loaded it into my TTO razor and lathered up for a basic shave test. Sharpness was nearly absent. I had to make repeated passes over my average beard stubble to get even the remote semblance of a passable shave. Longevity is roughly non-existent with CVS DE blades. One or two shaves renders these blades unusable. The only acceptable facet of this blade purchase was the blade dispenser, featuring a blade safe on the back of the dispenser to dispose of used blades. In short, pharmacy-brand razors seem to pander to price rather than quality. Save your money and spend a little extra coin on quality name-brand DE blades.
