So cute, so much fun. I don’t know what they’re made of, but I believe it’s some sort of printed vinyl foam core? Whatever it is, it looks great and weighs NOTHING. Tail hangs from a jump ring. Surgical steel posts. A couple of inches long. Worn a few times but in like new condition. Cleaned and sterilized. Pic #1 is a stock photo. All sales are final. If you have questions, reach out to me—I’m always happy to help. 😃
