check out Ikea!! But for now I needed something!! My collection was out growing my ziploc bag. Yes you read that right ziploc bag. So with trusty google I searched high and low for what people were using to store their Copics. I found some great and some not so great and some totally unique.
The best one I found was on this blog
So this was the one I used. I don't think mine is as flash, but it's definitely functional.
