The durable signature folders with 20 pockets and a dirt-repellent plastic cover are ideal for sorting and presenting daily mail and release documents. The extra-strong pages made of gray cardboard with practical flip tabs are particularly tear-resistant and protect the documents from slipping out due to their rough surface. The three viewing holes make the folders especially clear and help to quickly review and process documents. Thanks to their sturdy plastic cover and expandable spine, the signature folder is a particularly resilient organizational tool, especially with frequent use of multi-page documents. The field in the cover allows for individual labeling of the folder.
