So I've been collecting Copic sketch markers for some time now. Each color group has found itself in its own little bucket on my desk. Well, we all know how many color families there are which = lots of little buckets on my studio desk which = LOTS OF WASTED desk space. I picked up 6 of these and WOW, the organization (and extra space I now have on my desk) is FABULOUS. I have stacked 6 of these on top of another (positioning them with a slight backward tilt) and it is perfect for ALL the copics I have and makes them easily accessible. So long buckets!! Still trying to figure out why I waited so long to get these!
