Formular stationery

1938 registered envelope from the Bahamas. Although the indicium includes only the registration fee and there is no prepayment of postage, it is regarded as postal stationery and not formular stationery as the registration fee is a fee for a postal service. This and many other envelopes were made from thick paper and lined with glued gauze to make it stiffer and non-transparent.
1943 Air Mail Letter Card. The fact that it has an adhesive stamp and no prepayment of postage means that it is formular and not postal stationery.

The term formular (often misspelled formula) is an adjective applied to envelopes, cards and aerograms, etc., produced by postal authorities or to their specification, but bearing no imprinted or embossed stamp or other indication of prepayment of postage.

Formular stationery require the addition of an adhesive stamp before posting.[1] Formular items do not technically meet the definition of "postal stationery" (since there is no prepayment of postage), but the strong likeness to it secures them a place in many postal stationery collections.[1][2]

Countries such as New Zealand, Zimbabwe and Ireland, have printed unstamped aerograms.
