Had left me when buying on other reviews and was thus correct. Cartons are delivered folded flat. The folding of the carton is printed simple and understandable. What strikes a positive double reinforced cardboard ground, resulting in the construction. Even when folding the reinforcement into the ground everything closes pretty tight from the cardboard walls. In the short covers the cardboard pages handle amplifiers are incorporated, which are folded down and thus provide increased tear strength. A side cover remains nevertheless. Have the boxes used for books, picture books and records. Not one box gave up the ghost during the move (have however been made from time to time when packing out of consideration for the Umzugshelfer a lifting sample so that the boxes are not too heavy). Of the boxes used in the move they were here the best (initially had only 25 bought and then mixed with DIY cartons and existing). All other cracks partially while carrying on the handles a, buckled at the Fußecken or not coped lateral drawing. Would I buy it again.
