The mini binder clips are a staple among my office supplies. Unlike large and small paper clips which can catch on other sheets of paper (possibly adding an unwanted sheet to the batch) these grip the sheets that need to be kept together. I use all the binder clip sizes but was especially thrilled to find the 'mini' -- it's the ideal replacement for 2" paperclips. The Staples brand works just fine. As I say I would be lost in my work and personal filing without them.
I am not a "name brand" snob but I don't want to save money if it means an inferior product. Everybody is familiar with a binder clip and its uses but I wanted to review this as a "Staples" brand product. I always save myself a few bucks and order the Staples binder clips because they are equal in quality to the name brand. Don't waste your money -- buy the Staples brand binder clips. I have virtually every size in my office from mini to extra-large and they are all great. The mini clips are a great alternative to paperclips and do not damage or get caught on the paper.
