Lbxgap 168 Slot Pencil Roll Wrap Up Pencil Pouches Holder，Travel Drawing Coloring Pencil Roll Organizer for Watercolor Pens or Markers, Pencil Case Organizer for Artist

I have three of these - one each for Prismas, Polychromous, and Crayolas. I have a harder backed case like the one someone linked to above that holds 500 pencils and has about six smaller pencil sets, and then several of thesehttps://a.co/d/0cw56msI for gel pens and some markers. Some things - pastels, neocolors, and acrylic and alcohol markers stay in their original cases. My favorite are the rolls. They are cheap, and I can take them on the go (important for me because I get frequent all day medical treatments and I can throw one roll, a pencil case with erasers and such, and a book and be easily on the go). I have too much!
