Binder dossiers, just like ringed dossiers, can be used to store documents. The binder rail is usually made of a plastic plate equipped with two small metal flaps, serving to fix the perforated documents. The simple structure of the binder mechanism makes it usable only in case of smaller amount of documents.
Binder dossiers are typically made without saddle, but there are versions that can be fixed in a collector folder. It is recommended mainly for office use, excellent choice to store documents systematically.
