Copier tabs are perfect for organizing year-end reports, presentations, proposals and more. 90 lb. index stock provides the right amount of stiffness to stand up to abuse and ensure superior runnability. Three-hole punched design makes them ready for placement into standard-size binders. A smooth surface gives better imaging and improves printer and copier performance. Blank divider tab sheets are single straight-collated and designed to work in Xerox 5100, 4135 and other single straight-collated, tab-enabled printers. Each set contains five tabs.
