FAQs

Are these boxes suitable for international shipping?

Yes, they can be used for international shipping, but you must ensure the items inside comply with the destination country's customs and mailing regulations.

Can I use tape on these boxes?

While the earlock design is intended to be used without tape, you are welcome to add tape if you prefer additional security for your shipment.

What is the maximum weight capacity?

These boxes are designed for Large Letter items; please refer to current Royal Mail weight limits for Large Letter services to ensure compliance.

Are these boxes recyclable?

Yes, they are made from corrugated cardboard, which is widely accepted in household paper and cardboard recycling programs.

Can I print directly on the surface?

The boxes feature a smooth surface finish that is generally suitable for standard labeling, though results with home printers may vary.

Troubleshooting

Box lid pops open during transit

Ensure the tuck-in flaps are fully inserted into the side slots; if necessary, add a small piece of security tape for extra peace of mind.

Creases are difficult to fold

Run a thumbnail or a bone folder along the score lines before folding to ensure a sharp, clean edge.

Pros and Cons

Pros

  • Cost-effective shipping via Royal Mail Large Letter rates
  • No tape required thanks to the secure earlock design
  • Professional, clean aesthetic for business branding
  • Fast and intuitive assembly process
  • Space-saving flat-packed storage

Cons

  • Single wall construction offers limited protection against heavy crushing
  • Not suitable for fragile or breakable items
  • Fixed dimensions limit the size of items that can be sent

Setup, Compatibility & Care

Assembly is designed to be straightforward: simply fold along the pre-scored creases to form the tray, place your item inside, and tuck the side and top flaps into the designated slots. Ensure the tuck-in flaps are fully pressed into the locking mechanism for a secure hold. For storage, keep the flat-packed boxes in a cool, dry area to prevent moisture from weakening the corrugated board. Avoid stacking heavy items on top of the unused, flat-packed inventory to keep the creases intact and ensure they fold cleanly when you are ready to use them.
