You can pre-register the packing size/weight of cardboard boxes you use frequently for international shipments.
Please name the preset, input the sizes (length x width x height) and weight (optional), and "Save". It is possible to register only the size without entering the weight.
The packing presets list is displayed in a pull-down menu on the order page, when you click "...” at the left of the size fields.
If you have selected special packaging materials for DHL or FedEx on the "Carriers" settings page, they will also appear on this list.
