When it may not be suitable

These mailing bags are not designed for shipping fragile items that require rigid structural protection, such as glassware or delicate electronics, unless additional cushioning materials are used inside. They are also unsuitable for oversized goods that exceed the 400x500 mm dimensions or heavy items with sharp edges that could puncture the plastic film.

How to use

Place the items or documents inside the mailing bag, ensuring the contents do not exceed the capacity or dimensions of the envelope. Remove the protective strip covering the adhesive closure flap.
