12 vintage brass swivel snap links Italy 9 heavy duty

Up for sale is a lot of 12 assorted swivel snap links. Seven are heavy duty brass marked Italy; one of these has the spring missing. Another one about the same size is tarnished white metal. There is another heavy duty brass one (not marked Italy), that is slightly bigger and thicker than the Italy ones. I also included a brass ring which looks like it matches the heaviest snap link. There are two unmarked copper-plated swivel lobster clasps and one very, very small swivel clasp. With the exceptions of the one that is tarnished, and the one missing a spring, all appear in excellent vintage condition.
