One of the problems with dark file boxes is that if you have more than one you have to lift the lids to see what is inside. With clear ones you can see what one is full or which one has the spare folders or maybe the labels or tabs on the files holders.
Best deal going. Compact files fit perfectly stackable cover fits tightly. I have four boxes; one just for folder supplies holding my colorful folders ready for to be used.
I already have several of these hanging file boxes I have found them to be ideal for storage of information from several genealogical groups that I belong to
