For Copic Markers - This is a cheap CD holder with a CD case in every other slot! You can take out the paper label and color its spine to match your marker pens, put it back in the CD, and put your markers on the CD shelf.
Great idea for organizing the kids stuff! Take yards of DVD storage and condense it to a few inches. I do this with all of my music cd's as well! I also color code my music library; red notebook for Christmas, black for Classical, etc.
