8mm closed jump ring(16 ga. )
I USE THESE FOR ONE END OF A CLASP, WHEN I USE A SMALL OR MEDIUM LOBSTER CLASP
These closed jump rings have a nice shiny silver appearance and a good solid feel. Most of the quantity I ordered were perfect, while others were poorly soldered, with some having rough spots from the solder and others not being soldered in a perfect circle (i.e. the joins were not perfectly closed before soldering).
Overall, I think the quality of these jump rings would be fine for jewelery making, however, I was using them to make stitch markers for knitting and was unable to use the less-than-perfect ones as they would snag the yarn.
