These super-thin, reinforcement label rings are designed to strengthen and repair punched holes in binder paper. Self-adhesive white rings reinforce without covering up information and are permanent. The reinforcement sheets are punched with holes for easy storage in a three-ring binder. Apply the reinforcements to your standard-size punched holes to provide a durable border that resists tearing. Reinforcement labels offer 1/4" diameter holes. Your punched holes will be stronger for the experience.
