A box is a 3D object that is made from a flat surface. This means that all three main dimensions (width, height, length) need to be taken into account in order to know what the largest box is, that Slimbox can make. Slimbox can easily make boxes for things as small as jewelry up to things as large as parasols. But also almost anything in between.
The maximum size of the corrugated cardboard that you can enter in the machine can be found here.
