[This review was collected as part of a promotion.] The file box is plastic, and about the thickness of your standard tote. The lid flips open and closed and has a plastic snap lock to keep the lid closed. I did Drop the box twice to see durability and it held up with no cracks or breakage. It fits the standard size file folders if you want to put your stuff in file folders (not included) I have been able to hold a lot of documents and even a couple photos that I don’t want anything to happen too, and it still has plenty of space for me to add even more important documents. It is lightweight and easy to hold, while being empty and it will just depend on how much you add to it how heavy it would be, for me I am able to easily pull it out of my closet anytime I need to get something out of it or add something new to it. I do recommend this box if you are looking for a lightweight, durable, standard plastic file box.
