A2 Envelopes - 4 3/8 x 5 3/4

The A2 format is the standard enclosure for quarter-folded notes, reply cards, miniature announcements, and small gift enclosures. The compact dimensions (4 3/8 by 5 3/4 inches) fit neatly inside larger invitation envelopes, making them an indispensable element for multi-piece wedding stationery suites and formal event mailings.

Browse an extensive inventory of smooth wove stocks, frosted translucent vellum, rustic brown kraft, and glistening metallic foils. At JAM Paper, we carry A2 envelopes in the color you need to match your celebratory event palette.

Select elegant European contour flaps for luxury wedding response cards, or choose modern square flaps for handcrafted holiday notes. Available with traditional moisture-activated gumming or quick peel-and-seal strips, we package A2 mailers in 25-count packs for personal crafts up to high-volume cartons.
