At first I chose this to put my Inktense and Prismacolor pencils in, but I couldn’t bring myself to get rid of the tins, so I decided to use this and one other I purchased, to store my brushes in. If you use short brushes, they fit right in these, this is perfect, because I’m always worrying about them laying in a position that will keep the hairs straight. This is perfect for round and flat watercolor and quill or squirrel brushes..
