The reviews ran the gamut from fantastic to awful, and so far, I have to lean more toward the negative side, since the very 1st one I tried broke. The other ones I bought are great!
I was using small round leather cord for a eye glasses holder.( The kind that hangs around your neck.) The cord was too thick to close with a crimp bead. I was on the hunt. Spotted these & decided to try them out. I liked them but it was hard to find the right size.
These crimp end findings make design easy and fast. They look great too.
