Customer feedback reports that the boxes work with standard hanging files and can also hold regular files, with capacity and size noted as useful. Experiences with durability and value are mixed, and lid closure receives both positive and negative comments. For file storage, the reported fit aligns with the listed letter/legal ledges, but feedback suggests buyers should not assume every lid will latch securely or that durability will meet every expectation.
