How to use

Insert the B4 document or flat item into the mailer, making sure the contents lie flat and within the boundaries of the fold. Fold the flap along the 5.0 cm crease to create the expanded capacity if needed, then seal the mailer according to the chosen shipping method (adhesive strip, tape or postal sealing).
