Gillette Mach3 - 8 Cartridges Bulk Pack

Excellent product, great value and fast shipping. I haven't bought a razor blade anywhere else since the first time I ordered from greatrazors in August of 2007. I am and will continue to be a regular customer. My order history: Aug 29, 2007: Ordered a 4-pack of Mach3 cartridges just to see if the claims were true after reading a good review at http://www.headshaver.org/log/index.php?itemid=19 Dec 28, 2007: I ordered an 8-pack of Mach3 cartridges because the last of the 4-pack was finally getting a bit dull. The claims are definitely true. Aug 19, 2008: I ordered a 12-pack of Mach3 cartridges because I had just put the last cartridge on my razor handle and didn't want to run out. Sept 03, 2008: The last blade from the old pack will probably last another week or so before I have to toss it and open the new 12-pack. In the meantime, it's still giving a good shave. That's an average of a cartridge per month - incredible! The secret to making these blades last as long as possible is to rinse them in cold water. Hot water damages and warps the delicate blades. I found this out when I forgot to rinse with cold water and my blade's edge suffered noticeably from one shave to the next, which is unusual for these cryo'd blades. Even the cryogenically-hardened metal of the blades cryo'd by greatrazors is subject to warping and cracking under heat stress. If your blade clogs, rinse more often, or swish it in a cup of cold water. Your blade and your wallet will thank you.
