The County Stationery Board Back Envelopes are designed for professionals and individuals who need to send important documents, certificates, or photographs that require structural protection during transit. These C4-sized manilla envelopes offer a reliable peel-and-seal closure for efficient processing, though users should note that the rigid board back increases the weight of mailings compared to standard paper envelopes.

Yes, these are C4 size, which is specifically designed to accommodate A4 documents without folding.
Yes, the manilla material is thick and opaque, ensuring privacy for your documents.
No, these use a convenient peel-and-seal strip that requires no moisture.

While durable, these are standard mailing envelopes and are not explicitly archival-rated for long-term photo preservation.
Ensure the surface is free of dust or debris and apply firm, even pressure across the entire length of the flap for 5 seconds.
While the board-back protects the center, consider adding a clear 'Do Not Bend' label to the exterior if mailing highly delicate or fragile items.
To ensure the best results, place your document flat against the cardboard backing before removing the adhesive strip liner. Avoid overstuffing the envelope beyond its capacity, as this can weaken the side seams. Store the envelopes in a cool, dry environment away from direct sunlight; extreme humidity or heat can affect the integrity of the peel-and-seal adhesive. Since these envelopes are size C4, ensure your mailer fits within standard large letter dimensions to avoid additional surcharges.
