So you've spent a fortune on Detolfs, but your collection is still cluttered. Maybe the Spicy Shelf would be a good option, to create different "layers" in each level.
Especially if you have a lot of small figures, this would be a nifty way to raise them up. You can order them from the infomercial site, from Amazon, or even wait until they show up on that "As Seen on TV" endcap at Target. If you try it, let us know how it works.
