Expensive .... YES!! But, USEFUL!! My Craft/Office is small but when I saw the Ad/Video for these boxes I immediately thought they would be so useful for color sorting my scrap paper. Originally I had the papers in hanging files in two storage boxes. Did I go to them as much .... NO!! These boxes are perfect. I can see the color and do not have to spend time with labels but might later. I have 30 boxes (5 racks) and they are just down the back hall in the garage ...... not many steps from my Craft Room. I use white scraps more in my Greeting Card Making (I teach weekly Classes) and right now five boxes are designated for that category. Some of the boxes have cut and scored card stock ready to be used. All is perfect for me!! It is VISIBLE storage!!!
The storage system is a good idea, but if you now have your stash in the plastic storage carts, you can't get it in the storage boxes. I was hoping to replace all my carts, but that is wishful thinking.
