This product pro is limited to its use. Otherwise I wouldn't buy it. These clips rust after about 6 months especially when you use them to clip files of papers that you might not use for a while when you find them again the clips have rusted on the paper and you can't get the clip off the paper without tearing it. I have looked at other store for clips and they are pretty much the same thing so now I have decided to store all my files electronically so that I can have them after 6 months without the rust marks.
