Review on 🪒 Pack of 500 Single Edge Razor Blades by Derby Professional for Straight Razor by Donna Lewis

I bought these razors to carry in the RED blade holder of my Dovo Shavette. I bought these because there seems to be no source other than Dovo for longer blades that come in a BLACK holder. These blades are inexpensive enough to use a new blade every day without the need for sharpening or truing. Some reviewers complained about sharpness or quality, but I had no such issues. I love that they are individually wrapped and don't have to be broken in half like Dovo blades. Now I take a new blade, unroll it and assemble it, shave it, remove it and re-wrap it in wax paper for disposal. find a few (>10, <20) that seemed normal but I couldn't shave with them. Often these blunt blades stood in a row. If I had experienced these blades at the beginning and not at the end of the box, I would have been dissatisfied and would have complained about the product. I subsequently downgraded my rating from 5 to 4 stars due to poor quality control. If this were implemented, the price per box could be higher, so it's a compromise.
