A black Fimo snake is formed around a rubber band.
After hardening the figure is hanged on a heavy metal sprang, (base chain or neck wire).
The figure can be hanged on different kind of base chains. If you want a rubber or nylon sprang use listing: https://www.etsy.com/listing/96842545/rode-fimo-slang-ketting-met-rubber
and tell me that you want the black one.
If you want to have this nice metal sprang with one of the other snake necklaces, you can use this listing.
Fimo is light, strong and still a bit flexible.
With this beautiful base chain this necklace is very chic and eccentric. It is simple, but that’s the strength.
