This file is for a small folding cardboard box, which will snugly fit a 62mm x 62mm x 86mm square jar. It's designed to be cut from 6mm thick corrugated card. Assembly is as easy as folding the box together and fitting the tabs into slots. The file itself contains a basic guide to scaling. You can also upload a file for a 100mm x 100mm x 120mm box (internal dimensions).
