Interesting Vintage Black Overlapping Circles Necklace

Perfect for elevating any outfit to something a little...darker.
Interesting design - graduating overlapping black circles, which move
slightly as you move.
It's made of plastic so is very light and easy to wear - it sits comfortably
at the base of your neck.
It has a simple clasp at the back that allows you to adjust the length.
Found in an old warehouse so excellent unworn condition.
