How to use

Place the item flat inside the mailer so it sits against the bubble lining, fold the flap down and remove the protective strip to expose the adhesive.

Label the exterior clearly with recipient and sender information and apply postage as required.

Usage recommendations

Avoid overfilling the envelope beyond its inner dimensions to prevent seam failure. For heavy or sharp-edged items, use a rigid postal box or add reinforcement to the contents to maintain protection during handling.
