This necklace is made on a black suede cord. I used a black and deep pink plaid guitar pick as the charm. 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. I can also change the cord if you prefer a different color, or suede. Suede is available in limited colors. All of my jewelry and accessories are handmade by me (Bethany) or Jennifer. Made in and shipped from Lubbock, TX. USA
