The Swingline 646 Durable Full Strip Desk Stapler delivers reliable, everyday stapling with a sturdy metal die-cast base and plastic cap built for long-term use. It fastens up to 25 sheets of paper when used with Swingline S.F. 4 Premium Staples and holds a full strip of 210 staples to minimize reloading.

The stapler features a 3 3/4-inch throat depth for stapling further into a page without crumpling paper. A button latch allows the stapler to swing open for tacking documents to bulletin boards, and a rotating anvil enables pinning to create temporary staples. An antimicrobial coating helps prevent bacteria and mold growth, making it ideal for shared workspaces and copy rooms. Backed by a limited lifetime warranty.
