I know ten or fifteen years ago their stuff was split between USA and somewhere offshore (Taiwan I think). I haven't exactly kept up with them, so I'm not sure where their production is based now. The usual trend is to move offshore, but some companies have bucked that for the sake of their image (or genuine ethics I suppose

).
Either way, they're not going to be using an off the shelf blank, and their printer is not likely to be available for anything less than very large quantities (if at all).
