A cassette (2) or storage box for integrated circuit wafers or memory disks arranged and constructed for directly being placed onto the driven rollers (6) of contaminant free conveyors. The cassettes have a flat canted surface (10) for riding on the rollers. The cant is enough such that the loaded wafers lean against the sides of their individual pockets as the cassette travels. The leaning reduces damaged to the wafers by the vibrations involved with physically moving the cassette.
