User Reviews about Swingline S.F. 13 Heavy-Duty Staples - 0.5 Inch Leg Length - 90 Page Capacity - 1000 per Box (35312)

I requested and received a heavy duty stapler. It did exactly what I wanted it to do. -- Review stapler

These staples are strong and staple tightly to the paper without hiccups (jams, misfires, more than one staple per use, etc). These staples are used with a Swingline 210 Sheet Capacity stapler (of course). -- Swingline is Great as Usual

I use these in conjunction with my Swingline heavy duty stapler, which recommends these for stapling 40-90 sheets. I'm a graduate student, so most of the things I print fall in that range, and I've never had a problem with these staples. If you're starting an academic career, stock up on them. -- My default staples

These staples are extremely effective at holding thick stacks of paper together. But the edges are very sharp, so when you are stapling, be sure you keep your fingers out of the way. -- The Hold Things Together
