The ProFolio Sidekick zipper case is a magnetic case designed to attach to your favorite journal or notebook. The case allows you to carry multiple pens, pencils, markers, or erasers - all your essential tools. It can also be used to hold keys, makeup, business cards, cash and other items you need on a daily basis. Attach it to binders, books, presentation books, files, briefcases, bags, purses or clothing. The back flap can also be used as a bookmark since the magnets are strong enough to go through roughly 50 pages.Details:Available in assorted colorsMulti-purposeBack flap can also be used as a bookmarkDurable nylon construction
