How to use

Place the item in the centre of the padded envelope without forcing or overfilling the mailer.

For added protection, wrap particularly fragile items before inserting them into the mailer. Ensure labels or addresses are attached to the exterior surface in a clear, visible position.

Usage recommendations

For best results, choose the correct size mailer to avoid excess movement of the item inside. For high-value or particularly fragile goods consider double packing or adding additional internal cushioning. Store unused envelopes flat in a dry environment to maintain adhesive performance and bubble integrity.
