Cloud 9 is correct. I shot the Carbon Express 400s for a couple years with relatively favorable results. They are a bit on the heavy/stiff side compared to most of the other typical ICS shafts on the market...comparable to a Beman ICS 340...as that is what I am shooting now. $37 for a half dozen is a good deal provided they are in good condition. I would check to make sure there are no cracks around the nock area...my only real complaint about them.
