The folding box can be flat (as not expected otherwise) wonderful store. Spread can be employed provided for better stability floors. For small parts a small net is sewn into one of the two subjects, very practical. What I really like, the plastic handles. This allows the box very well carry, even with heavy weight. The handles are inserted and at first use is an easily gone apart. Simply compressed again and since then keeps everything together well. If that happens again, I would use glue.
