$22 or so for 8 which is cheaper than the $30 horizon is asking for the SP kit. Also says double shielded and teflon sealed, which I'm assuming means really high quality (tho I dunno what the abc sp bearings are). Also noticed that the thickness is 2.3mm instead of what I assume is the standard 2.5mm
