How to use

Insert documents carefully to avoid creasing, aligning the top edge with the open side of the envelope. For mailing, place any required address label and postage on the exterior surface, ensuring the contents remain visible if a transparent address window is used. Store envelopes flat in a dry place away from direct sunlight to prevent deformation. When removing documents, hold the envelope steady and slide contents out gently to preserve paper edges and printed surfaces.

Usage recommendations

Use these transparent C3 envelopes for non-sensitive documents that benefit from visual inspection without opening. For long-term archival storage or sensitive materials, consider additional protective measures such as acid-free sleeves or rigid mailers to prevent bending and environmental degradation.
