Designed for e-commerce businesses and home users who frequently ship slim items, these C5 postal boxes are optimized to fit within Royal Mail Large Letter size guidelines to help minimize postage costs. They provide a secure, professional shipping solution for documents, media, and stationery; however, they are single-wall constructions and are not suitable for fragile or heavy items that require heavy-duty protection.

Yes, they can be used for international shipping provided the contents meet carrier weight and size regulations.
They are designed for single-use, but they can be reused if the cardboard has not been creased or torn during the initial transit.
While the earlock lids are secure, using a small piece of adhesive tape is recommended for added security and to prevent tampering.
These are designed for light, slim items. Please refer to Royal Mail's Large Letter weight limits to ensure compliance.
Yes, they are made of corrugated cardboard and are fully recyclable in standard paper/cardboard waste streams.
Ensure all side flaps are fully folded and locked into the earlock mechanism. Use a small piece of shipping tape if the contents are tight.
Ensure you are not overstuffing the box. Single-wall construction is designed for slim items; if the box is bulging, the contents are too thick.
Use a layer of bubble wrap around the item before placing it in the box to add a buffer between the contents and the box walls.
Assembly is straightforward: fold the side panels upward, wrap the back panel over, and tuck the earlock flap into the designated slot. No tools are required, though you may use clear shipping tape to reinforce the edges for added security during long-distance transit.
Store these boxes in a cool, dry environment. Moisture is the primary enemy of corrugated cardboard; storing them in a damp area can weaken the fibers and compromise the structural integrity of the box. Ensure they are kept flat until use to prevent pre-creasing or accidental deformation.
