I use these all the time for employee files and special projects. The pressboard is not flimsy so great for carrying in the field. Great to have separate areas to organize your projects with the fasteners. Ease of accessing you documents.
These pressborard fastener folders are very durable. We use these for all client files. These files are accessed many many times. Many folders are used weekly for a year or more. The folders offer a good capacity and when dividers are added we can customize the sections as needed with out sacrificing usability. I would recommend these to any office needing durable folders with fasteners. The per folder cost is high but considering we don't have to replace the folder when it wears it is worth it.
