My firm has been making die-cut black cards for years. They are
chiefly for earrings, tie-tacks, and button covers.
Die-cutting has to take place for any special size, shape, and
perforations on your card. Die-cutting ain’t cheap here in the
states, and I don’t know about Saigon. Maybe cheaper there, what with
a longer history of paper use, and lower labor costs.
Perhaps a one-size-fits-all approach, with your business card doing
double duty, with printed info stickers on back. Include area to
accomodate price on each card or tag.
