The ProFolio Journal Sidekick Zipper Case is a magnetic case designed to attach to your favorite journal or notebook. The Zipper 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.
