This is a box full of tiny alligator clips. I use them to hold the tarp and projector screen together since their grommet holes don't line up. I also use them as cheap pocket clips. The teeth hold up well, they are cheap and small. My only complaint is that the part you press is a bit bulging. I understand it's all metal but wish there was something to close that space or if the physical design was a little different to make opening the clamps a little easier and less likely to bump.
