I won 7 different auctions for Gillette blades M3 Mach from 2 different sellers. Please beware of the blades you buy from Sellers. I cut my face pretty bad on the blades that I won from these Sellers. After many emails and threats, I got my refunds from these sellers. How can you buy a 8 pack of these blades for under $1.00 When they sell for around $ 20.00 in the stores? Seems that the Sellers know they are bad, So they sell them cheap to get rid of them. Please check out the website FAKEBLADES.COM You can find out if your blades are from Gillette or are fakes. PLEASE WATCH YOURSELF WHEN BUYING THESE BLADES, YOU CAN GET CUTUP PRETTY BAD !!!
