La Poste prepared a booklet of twelve top-up stamps for use with 2027 postage. It contains four 15-cent stamps intended to supplement the 2026 €1.52 domestic 20 g Lettre Verte rate, four 20-cent stamps to supplement the €2.25 international 20 g rate, and four €1 stamps for other postage combinations.

Olivier Balez designed the stamps, Pierre Bara engraved them and Arobace designed the booklet graphics. The stamps are intaglio printed. The announced printing was 50,000 booklets, at €5.40 each, with a preview at the Paris autumn salon.
