Unique, reduced-effort, PaperPro One-Finger spring-powered technology makes stapling 12 sheets of paper an easy squeeze. Small enough to fit in a pocket, this mini stapler is perfect for the home office, school or work. For easy access, a key chain can be clipped onto the metal ring on the back of the stapler. Jam-free operation delivers smooth, repetitive stapling. The InCourage 12 Nano Stapler uses standard staples. A portion of the proceeds from the purchase of this stapler will be donated to cancer charities via the AMAX Spirit Foundation. More from the Manufacturer.
