I used a black guitar pick with an orange and white Chinese Opera mask printed on it. I used rolled black cord. The necklace is 18 inches around and extends to 20 inches. If you need it to extend further let me know and I can add more of an extender chain to it. I used a lobster claw clasp, but if you prefer a barrel or toggle clasp let me know and I will change it. All of my jewelry and accessories are handmade by me (Bethany) or Jennifer. Made in and shipped from Lubbock, TX. USA
