Envelope, straight flap. The same envelope with a straight rather than pointed closing flap. Cheaper to cut, and it gives a wider area for a seal sticker or a printed message.

Not yet plate-checked. This template folds, closes and exports cleanly, but its blank has not yet been matched against the standard's own drawing in detail. Treat it as a starting point and check it before you spend anything.
