When storing pages in a binder, it can be valuable to create sections that help to refer to specific material. This will eliminate having to search through the entire binder. Index dividers are commonly paired with binders to help divide and organize the information. The multi-pocket index dividers not only create information sections within the binder, but they add additional storage space for loose papers. Use the acid-free polypropylene dividers to store up to 8 1/2'' x 11'' size documents and smaller. Write-on index tabs allow you to instantly categorize your binder and label each section to make it easy to reference. Use a pencil, ball point pen or permanent marker to label each tab. Each divider features two pockets making it possible to organize pages, business cards, notes and more. Index Divider Style: Customizable; Index Divider Size: 11.5 x 10; Punched/Unpunched: 3-Hole Punched; For Use With: Ring Binders.
