I found a storage solution and it was quick and easy to make. This will only work for Copics. I have some Spectrum Noir Markers and they are too fat for the squares in the lighting grid.Here is a link
to the site I have saved on Pinterest.
Here is a picture.
I found the really useful box at Office Depot for 11 dollars. The suspended lighting grid at Lowes for around 10 dollars. I have enough grid to make another box. (It comes as one big panel) Cut the size for the box with a hacksaw and hot glued grid in the box. One on the bottom and one at the top.
Some people say their markers don't fit well but I found if you turn them slightly and put the marker in the box with the chisel end down, you will have no problem getting them in and out.
