IRIS USA File Box Slim with Lid File Organizer for Letter File w/ Organizer-Lid, Water Resistant Document Box, Plastic Mobile Filing Organizer, Secure Buckle, Portable Handle, Lockable, Black 4 Pack

The IRIS USA File Box Slim with Lid is a versatile and practical solution for organizing and transporting documents. Measuring 13.38 inches long, 6.5 inches wide, and 11.75 inches high, this file box fits letter-size hanging file folders and provides a convenient ledge for easy access and organization. The included 4-compartment lid organizer is a thoughtful addition, allowing users to store small office supplies such as pens, thumbtacks, and clips efficiently.

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. The secure latching lid ensures the contents remain intact and protected from spills or unauthorized access, and the lock spot provides an extra layer of security for sensitive documents. 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. Additionally, while the water resistance is a plus, it is not entirely waterproof, so it may not be suitable for extreme conditions. This product is best suited for professionals such as bankers, financial advisors, or anyone who needs a reliable and portable solution for document organization and security.

Buying Guide for the Best Portable File Boxes

Choosing the right portable file box can make a big difference in how you organize and transport your important documents. Whether you need it for work, school, or personal use, understanding the key features will help you select the best option for your needs. Here are some important specifications to consider when picking a portable file box.
Size and CapacitySize and capacity refer to how much the file box can hold. This is important because you need to ensure that the box can accommodate all your documents without being too bulky to carry. Small boxes are great for minimal documents or personal use, medium boxes are suitable for moderate amounts of paperwork, and large boxes are ideal for extensive files or professional use. Consider how many documents you need to store and choose a size that fits your needs without being overly cumbersome.
MaterialThe material of the file box affects its durability and weight. Common materials include plastic, metal, and fabric. Plastic boxes are lightweight and often waterproof, making them good for everyday use. Metal boxes are more durable and secure, ideal for important documents that need extra protection. Fabric boxes are lightweight and flexible, suitable for casual use. Think about where and how you will use the box to determine the best material for your needs.
Portability FeaturesPortability features include handles, wheels, and shoulder straps that make it easier to carry the file box. Handles are standard and useful for short distances, while wheels are great for heavier boxes or longer distances. Shoulder straps can provide hands-free convenience. Consider how often and how far you will need to transport the box to decide which portability features are most important for you.
SecuritySecurity features such as locks and reinforced corners help protect your documents from theft and damage. Locks are essential if you are storing sensitive or confidential information. Reinforced corners and sturdy construction can prevent damage from drops or impacts. If security is a priority for you, look for boxes with these features to ensure your documents are safe.
OrganizationOrganization features like dividers, folders, and labels help keep your documents sorted and easy to find. Dividers and folders can separate different types of documents, while labels make it easy to identify contents at a glance. If you have a lot of different documents, these features can save you time and keep you organized. Choose a file box with the right organizational tools for your needs.
Weather ResistanceWeather resistance refers to the file box's ability to protect your documents from elements like water, dust, and humidity. This is important if you need to transport or store documents in varying conditions. Waterproof boxes are ideal for protecting against spills and rain, while dustproof boxes keep out dirt and debris. Consider the environments in which you will use the box and choose one with the appropriate level of weather resistance.
