Be sure to read these Razor blade auctions Very Carefully! Some sellers are advertising blades as "New in Package" and then lower down in the auction, in tiny print they mention "These blades are 2nd quality" or  ""No Refunds" or "As Is" "What they don't tell you is that these "2nd quality" blades are virtually unusable. Many are counterfeit and not actually made by Gillette. The blades are dull and will rip and tear your skin while failing to cut hair. Some of the blades don't even fit the handle securely and fall off. 2nd quality actually means rejects that don't work and shouldn't even be sold. They feel like they've been used and the blades have been dulled down. There is also no lubricant in the lubricating strips, making the shave even worse. Search the web and you'll see the global problem with counterfeit blades and how to spot them. BE SURE TO CONFIRM THAT THESE ARE GENUINE  MANUFACTURER BLADES BEFORE BUYING! I purchased 40 such blades for the Gillette M3 and had to throw them all away. I am out $46.00. Don't let this happen to you!
