Smead Poly Index Dividers with Pocket are a great way to organize by color, day of the week or project. High-quality, tear- and water-resistant polypropylene construction delivers increased durability, and oversized tabs provide plenty of space for clear and concise labeling. A handy, translucent slash pocket on the front of each divider holds up to 10 sheets of paper, making it easy to keep track of loose materials. Ideal for work and school, they're also pre-punched for standard, three-ring binders, and they're easy to clean, too. Index Divider Style: Customizable; Index Divider Size: 11.25 x 9.75; Punched/Unpunched: 3-Hole Punched; Index Divider Material(s): Polypropylene.
