Vintage Elephant Walk Necklace…

I’ve seen a couple of these necklaces pop up on selling platforms, using different terminologies for the material used. Celluloid, plastic and other names. I don’t know myself the correct name, but it’s lightweight and free from cracks. Entire necklace measures 13” top to feet of bottom elephant. There are no markings anywhere. 5 elephants and rosette spheres dangle vintage necklace. Even tho it’s old, it’s nice and clean & perfectly “giftable”
