Setup, Compatibility & Care
Setup: These envelopes require no setup; they are ready for immediate use straight from the packaging.
Compatibility: The C3 size is compatible with documents up to 324 x 457 mm (12.75 x 18 inches). They are suitable for sending alongside standard mail and courier services.
Care: Store envelopes in a cool, dry place away from direct sunlight to maintain the integrity of the paper and the adhesive on the self-seal flap. Avoid exposing them to excessive moisture, which could cause the paper to warp or the adhesive to lose its tack.
