Questions about this box
Is the size inside or outside the box?
All sizes are internal (length x width x height), measured inside the box. The outside is a few millimetres bigger because of the board thickness.
What does the pack size mean?
The pack size is how many boxes come in one pack, for example x25 is a pack of 25 boxes. "Number of packs" sets how many packs you get, so x25 with 2 packs is 50 boxes.
Are the boxes delivered flat?
Yes. Regular cartons are delivered flat to save space and fold into shape in seconds.

Use 48mm packaging tape along the top and bottom seams. For heavy items, also tape across both ends. See "How to fold & seal" above.
