A system to make an A5 or Half Letter format bookbinding, for 100 perforated sheets or more, with a standard hole distance of 80 mm . A heading could be wrote on the back.
Just put the 2 little sticks in the main flexible part (see picture), position the perforated pages, fold the main part and then lock the bookbinding with the key part by translating it.
