How to use

Insert the document or items into the envelope, remove the protective backing from the adhesive strip and press the flap firmly to seal. Ensure edges are aligned before sealing to avoid creasing or misalignment. Use a pen or label on the exterior for addressing; envelopes accept standard ink and adhesive labels. For heavier contents, consider reinforcing the flap with tape or an additional label.

Usage recommendations

Store envelopes flat in a dry environment away from direct sunlight and extreme humidity to preserve adhesive performance and prevent warping. For postal use, check carrier regulations for weight and size limits; avoid overfilling to ensure reliable sealing and handling.
