Side capacity, it is great, practical, ideal for storing letters or other papers in default; it seems more solid, cardboard is thick.
Finally aesthetically it is very beautiful, the details are cared - metal reinforcements, handle, label, bright and lacquered color ... We forget the cardboard side - no cheap side - and it fits perfectly into the setting for a office or a bedroom.
A good storage concept which is perhaps a fault for me - the price; to see over time, if it is really worth.
