Marketing Information: Find the strength your papers need to carry on. These super-thin, reinforcement label rings are designed to strengthen and repair punched holes in binder paper. Self-adhesive clear rings reinforce without covering up information and are permanent. They are made of super-thin poly vinyl that is four times stronger than paper rings. The labels come packaged in a handy dispenser that peels each self-adhesive reinforcement off the roll one by one. Apply the reinforcements to your standard-size punched holes to provide a durable border that resists tearing. Reinforcement labels feature 1/4" diameter holes.
