18-20" silver plated brass adjustable tubular metal-mesh chokers. Diameter is approximately 3mm round. The metal mesh is slinky like chain, not stiff. High quality. Silver plate nicely matches the color of actual silver. These chokers are finished with a lobster clasp and 2" extender chain.
I am very happy with this product (I ordered in silver and gold). It looks great with my pendants, is a good length (with the 2" extender), and is wearing very well. I haven't had any issues. For the price, i think they are perfect.
