Box top can easily rip the wall of the box when removed during construction. Top does not attach firmly enough for moving the box around. Box can be easily constructed by children and anyone. Box is sturdy enough as any standard box. I bought them for moving so I could easily have all the boxes needed without a mess or dumpster diving. Extras can be stored for later uses. It still is good looking enough for anywhere.
I was hoping I could use hanging files with these boxes (b/c I didn't want to pay more for boxes designed to do so) but the lids don't fit over the hooks hanging over the boxes' edges. Otherwise these are sturdy easy to assemble basic boxes that carry a lot of weight and keep files in place and organized. I'm a teacher taking a leave of absence who needed an easy way to store all of my files and may use some of the surplus boxes for moving.
Assembling the first one may be puzzling but from second on it's easy. Like the Tardis they seem bigger on the inside than the outside and are ideal for academic office storage and short-distance self-moving. Wonderfully inexpensive compared to alternatives.
