Sizing
Inside: 100 x 100 x 800mm (length x width x height)








Australian-made cartons in bulk quantities, from $0.87 a box. Trade accounts get invoice terms and a dedicated contact.
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.
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.
