I have been looking for some of these [SOM1-01](http://www.ourcuriousworld.com/SOM1-01.htm) document fasteners, which we can see in the photo, on the left side of the document. I was only wanting one or two, in a cheapie little notebook like, so I thought I could go to Wally World and get one. No luck, so, I thought I would go online and see how much they were, and I realized that I had no idea what they were called.  
Can anybody tell me?

Thanks

I’ve always heard them called “Acco fasteners,” and the ones on my desk right now are indeed marked “ACCO”.

They’re commonly called ACCOs, but the generic name is “prong fastener.”
