The plastic file organizers we purchased work great and are high quality. Their stackable and quite sturdy. Much better that my old paper file boxes. We found them cheaper on line (with Staple's) and the store matched the price. My only minor complaint - why do manufacturers apply stickers that are difficult to remove???
I have over the years purchased 5 of these file totes. I love the size fits files but not bulky. Even the colors you can see through what is in them. However one fell empty less than 3' & cracked in the corner. Different one I grabbed the box and cracked the corner just by the heavy shifting files.
