How to use

Insert the item to be shipped into the cardboard mailer so it lies flat against the internal surface. If additional protection is required, add a thin protective layer such as paper wrap or film around the item before placing it inside. Close the opening according to the mailer’s closure design and apply the shipping label or address information to the outer surface. Ensure edges and corners are aligned to minimize movement inside the mailer during transit.

Use these cardboard mailing bags for items that primarily need protection from bending and surface abrasion. For fragile or heavy objects, complement with internal padding or choose a more robust box. Store packs in a dry environment to maintain cardboard integrity and keep the mailers flat to preserve stiffness.
