Here a few of the options that were available at Arch, all very nice and most quite pricey (top to bottom): Cargo brand folders with black elastic closure -- different colors available (appx $10); Cargo brand presentation boxes, quite nice and simple ($30-$40); Century archival clamshell boxes (I think $40+); and Pina Zangaro aluminum boxes, super sleek -- perhaps too sleek (as well as too expensive, about $60 each). The Cargo folders are perhaps an option.
