Mostly personal use. Generally very good quality. I recently did purchase a 10 pack that had a manufacturing problem. After assembly the panels did not line up properly. Not sure if it was a stamping or creasing problem. Boxes were still usable. Probably have sixty boxes. Very happy with the over all quality/price ratio.
Good sturdy box. Great for storage. I fill with books and it is just the right size. Will hold as much as I can lift. Convinient handles. Top fits reasonably well.
