Anatomie d'une pochette : ce qu'elle contient
Article en anglais — traduction à venir.
A pocketfold is a folded pocket that holds the whole suite: the invitation card, an RSVP card with envelope, a details/accommodation card — all closed with a belly band, ribbon, or wax seal.
When quoting, count every insert: each card is a separate print run. The pocket itself is usually laser-cut or foil-stamped, which is where the perceived value comes from.
