Large Pencil Shelves Student Desk Stand Organizer with 96 Slots for Markers, Gel Pens, Colored Pencils, Ball Pens - Plastic Desktop Storage Box

The grid is too small for Copics (not even Ciao), Ohuhus, GraphITs - you name it. Don't buy this for alcohol markers unless they are unusually thin.

I has hoped to use these as storage for my Tombow brush pens and other brush pens. If your pen's colour marker is on its base then these are no good. You can't see the colours. I had hoped to be able to use these on their side but depending upon your pens the depth won't be enough. Perfect for occasional pens on a desk but not recommended for artists

Does exactly what it's designed to do. Hold pens 😊
