Abstract
This invention relates to a type of paper clip known as a binder clip. Binder clips are a class of clips -suitable for binding together thicker stacks of paper or other thin sheets, up to a stack ⅝ inch thick, or approximately 125 sheets. Typical binder clips currently available on the market are comparably bulky and heavy, and add thickness above the height of a stack. As an improvement, this invention has a quite flat, low and compact configuration and is light in weight, which overcomes these typical problems. Additionally, it can provide a flat surface to accommodate writing or advertising graphics.
