Yes, they are suitable for international shipping as long as the contents are lightweight and fall within the required dimensions for the chosen mailing service.
While the earlock lid provides a secure closure, it is recommended to use a small piece of shipping tape for added security during international or long-distance transit.
Royal Mail currently limits the thickness for a Large Letter parcel to 25mm.
Yes, these cardboard boxes are typically made from recyclable materials and can be placed in standard paper/cardboard recycling bins.
These are ideal for documents and thin items. For fragile items, consider adding bubble wrap or protective tissue paper inside before closing the lid.
Ensure the earlock tabs are pushed completely into the slots and that the box is not overfilled, as excess internal pressure can force the lid open.
Verify that all creases have been folded sharply to 90-degree angles, as correct folding is vital for the structural integrity of the box.
To assemble, lay the box flat and fold the side flaps upward, followed by the end flaps. Secure the base lock, insert your goods, and fold the top lid over, pressing the earlock tabs firmly into the designated slots. These boxes are designed to match standard Royal Mail Large Letter requirements, meaning the total thickness of the filled package should remain under 25mm to qualify for the specific mailing rate. Store these boxes in a dry, climate-controlled environment to prevent moisture absorption, which could weaken the corrugated fiberboard over time.
