While we live in a digital age, hard copies are still necessary---power outages and technological freak accidents happen. Back up your contacts with that old rotary filing index and fill it with these 3" x 5" file cards. They are available in two different card stock thicknesses: 65 and 67 lb., along with a wide variety of colors. This layout specifically has four index cards per page, with 250 sheets in a ream, yielding a total of 1000 individual cards, with tabs located in the center. These file cards will work on all copiers, digital, laser, inkjet, and offset printers. The perforations tear off easily and will give a smooth edge. The customizations are endless! * Other paper stocks and colors are available on request
