Storage!

Need a better system for storing my promarkers - ideas needed do I'm off for a google - I think they need to be stored on their side so the ink doesn't run, at the moment I have a manageable system - but it appears to have just failed me lol

So currently I have my promarker colour sheet filled in as I find I like the colours on paper rather than look at the actual pens as the paper gives a more accurate colour

I've split the colours up and numbered the relevant draw where they are - so if I'm working on a red piece all y reds are in the same place - I have to dig round sometimes and find the right red it's nothing major but now for example I can't find in the pink draw a certain pink! So I'm off draw diving to find it!
