Its size of 18.13 inches in length, 14.13 inches in width, and 10.75 inches in height, along with its 35-quart capacity, makes it a spacious option for document storage.

Portability is a key feature, with the boxes being lightweight at 2.11 pounds each and stackable, which helps in saving space and easy transportation. However, while the file box is water-resistant, it may not provide complete protection in severe weather conditions. For organization, the file boxes can fit both legal and letter-sized documents, making them versatile for different uses such as in offices, classrooms, or even at home.

One downside could be that it only comes with a single compartment, which might not be sufficient for users needing divided spaces within the same box. The stackable and nestable design is a plus for those needing to store multiple units compactly. This file box is particularly beneficial for users seeking a balance between capacity, durability, and secure storage.

The ENGPOW File Box's material also resists dust, maintaining a neat appearance. Although the product is lightweight at 2 pounds, it is robust enough to support up to 200 pounds, alleviating concerns about structural integrity. However, users should consider that, while the product offers significant protection, it is not entirely foolproof against extreme conditions.

Portability is a key feature of this file box, thanks to its sturdy handle that makes it easy to carry, and its lightweight design at just 1.55 pounds adds to the convenience of transport.

Made from durable plastic, the file box is water-resistant, offering some protection against moisture, which is beneficial for safeguarding important paperwork.

However, the file box's capacity of 9.5 quarts and weight recommendation of 10 pounds may limit its use for those needing to store and transport a larger volume of documents.
