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.
A plastic box is a plastic box. I just reviewed it to say Helen at the Grand Blanc store is amazing and deserves a raise for her customer service and her adorable laugh!
We had a large filing cabinet et back in the day when everything was kept on paper. Not necessary any more but there are a few documents we still keep. This was just the right size for downsizing but still keeping important documents in one place. It's light the lid fits great and the files glide nicely. Highly recommend.
