Necklace Neck Wire 18inch black cover over stainless wire 249x
An inexpensive option. Not sure if this would technically be called a neck ring. It is a 1 mm twisted steel wire that has a black plastic covering, flexible but holds it shape well with no kinking. The clasp is a screw closure similar to a barrel clasp. Did take me a minute to figure out how it unscrews as you can hold it 2 ways. Once you understand that simple to open.
