How to use

Place documents or items flat inside the envelope so they lie within the inner usable area without bending. Insert multiple sheets carefully to avoid overfilling and to ensure the flap closes evenly.

For postal use, attach the required postage and any necessary customs or tracking labels before handing to the postal service or courier.

Usage recommendations

For best results, do not overfill the envelope; keep contents within the inner dimensions to avoid stress on seams and to ensure reliable sealing. Use additional protective sleeves for fragile photographs or important certificates, and verify postal service size and weight limits when preparing items for mail.
