Self-adhesive dividers transform standard fastener folders into divided or classification folders. Made of 11 point heavyweight manila stock, dividers classify papers in up to four categories and feature standard, 2-3/4" slit punching. Scored design forms a self-adhesive hinge for attaching to folder. Dividers are hinge-slotted to fit around fasteners in folder. To create additional filing surfaces, add self-adhesive or twin-prong fasteners (sold separately) to your dividers.
