I love this rack! It is so versatile and saves so much space compared to other marker organizers. If you need to add more you can always get individual trays. But I suggest you get set to begin with! You'll wonder how you could ever have had anything else.
I ordered three of these to put on top of the pen storage I already had. I seem to be getting more and more colored pens to use in card making. These worked just fine as an add on and solved my storage problem. I am glad that I got three of them.
I really love these storage racks to hold my Copic Sketch markers. I originally bought a set of these racks. It is nice that you can buy individual racks as your collection grows. They stack nicely and it is easy to remove the markers from the rack.
Bought some twice but need more. They are great. I am using for my building collection of Spectrum Noir alcohol pens and glitter pens. Keeps everything in place and flat like you are supposed to store them.
I like the look of the see through racks. My only regret is that they aren't bigger !!?? Maybe I have too many Copics !! Very sturdy and love the blue hue to the plastic.
