corner gallery wall - without the specially made corner frames. Would need to be on a corner that is in an open area; this would be really overbearing in a tight hallway. But in the right space it could look amazing. Very art gallery.
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.
