ArtBins are great for any artist who needs some portable organization. Each bin is made of durable plastic and houses an array of compartments made to make finding all of your supplies a breeze! Inside this model you'll find a tray with one long compartment for brushes, pens, and pencils, two medium compartments, and three smaller compartments--all of which can be further separated using the included plastic dividers. This tray swivels back giving you easy access into the main storage compartment. External dimensions measure 15" long, 8" wide, 6.5" tall.
