Hey, these are pretty great! Early this morning I printed out 100 pages of a manuscript, then realized I didn't have any way to secure them (ha!). I ordered these rings because they were eligible for "same-day delivery." I also thought the bronze looked less likely to chip than the black ones.I was initially concerned by another review, which warned that these rings were hard to open—I have arthritic hands—but they opened OK! Instead of pulling the ends "straight apart" (horizontally) try pulling them apart vertically, so that the two "teeth" of the clip move out and away from each other. (Each clip snaps closed again very easily!)I don't think these rings are necessarily sturdy enough to stand up to a whole lot of open-and-close action, but if you just want a quick and simple way to bind a sheath of papers together like a book, they're pretty and maybe a little bit more elegant than a big, bulky binder. They seem like they would have many other practical applications, as well! I might not find uses for all remaining 47 clips, but I can sure try.
