Not only do you avoid the mess of having to remove those little metal annoyances, but you can also avoid the waste of refilling your stapler with them. The Staple Free Stapler offers you the convenience that the "old" stapler had without the inconvenience the metal strips gave.
In a little 2x2x2" package, this stapler will allow you to instead attach paperwork together using tiny strips of paper it cuts from the stack. Only works with a few sheets, they say five, but if you frequently staple two pages together and want an option NOT to use the metal staples, this would definitely make those dreams come true.
Safer for kids than the alternative, too. Comes in five different colors and sells for around $8 on this site.
