I wove this chainmaille choker by hand. Each patch of chainmaille, and large jumpring connecting them has a spike hanging from them. Don't worry, the spikes are not sharp and will not poke you. Choker color is black ice. Choker made using 18g anodized aluminum, spikes are acrylic. Lobster clasp. There are 2 choker lengths to choose from in the options list. The 13 inches + 5 inch extender (letting you adjust it between 13-18 inches) fits most adults, but there is a longer option available for those who need it.
