Pros : I have put these chains to the test. They passed with flying colors! I break things easily when I wear them and I was concerned about the thinner part (that slips thru a bead) breaking off the chain. NOT worried anymore! I have been selling my beads with these for years, plus using them myself. GREAT!
Cons : None
Other Thoughts : If you want to offer quality sterling with your quality art glass, these are perfect! My galleries LOVE them!
