The Swingline SmartTouch 3-hole Punch SWI74136 is designed for manual use, efficiently punching through 45 sheets at a time. Constructed from durable metal, it ensures long-lasting performance for all your punching needs. The soft-grip handle locks down for compact storage when not in use, and the hole pattern in the base allows for visibility into the chip tray to see when it's full. The pullout tray design makes it easy to empty when necessary.
