You can purchase these necklaces in my etsy shop, here:[link]
I am FINALLY able to debut this design after working on it for so long. I just shipped a bunch of them off to various boutiques and alternative shops. They're also available in my etsy shop now too in TWO different colors!
They are made out of plated base metals (both nickel and lead free). The gas mask is made out of the same metal material with a black coat of enamel.
