Sometimes accidents happen, especially with technology. That's why it's a smart idea to keep hard copies of contacts and information handy. 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. It offers per page two right-sided tabs and two left-sided tabs. 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
