Yep. Snake Bonz. Usually water moccasin; sometimes copperhead, and occasionally people find a random deceased snake and bring it to me to honor it in jewelry. (I really try to only kill the water moccasins. They are poisonous and vicious, and present a danger to the other wild things that live on my property).
Cleaned thoroughly, sterilized and allowed to dry an extended time in the sun before I use them. Absolutely safe for adults. As with most of my stuff, I don't recommend these for kids.
