This cube is from Ikea. Well made not difficult to assemble, however you Cropper Hopper paper organizers will not fit without cutting at least 1/4 to 1/2 inch off the top. It can be done, just not so easily. Love the amount of scrapbooking supplies which can be organized in these cubes.
Closetmaid pantry shelving to store ribbon spools is better than the dowel or hanger system because spools can easily be removed. My favorite storage is this one, and the ribbon card from cropper hopper.
