Perfect for any Detroiter or anyone who loves to ride. I am a collector of Shinola items being from Detroit but it is time to let this beautiful piece go and actually be worn by someone!!! Here are the details; the piece is no longer made so this is what I could find! The Bike Lock Charm really opens and closes—it’s spring loaded and secure, so you can lock up additional charms or add the Bike Lock to another piece of jewelry, a handbag, or keychain. With a beautiful, minimal shape, the Bike Lock Collection is perfect for standing alone or layering up. LOVE ON LOCK The humble bike lock ought to brag. It has a beautiful minimalist shape and a single pure purpose: to never let anyone steal your thunder. Crafted from 14k gold, our Bike Lock Charm Necklace is an elegant tribute to an unbreakable icon. Spring-loaded, it opens and closes with a pull and a twist. Wear it as a talisman on the adjustable gold necklace, or add it to another accessory to keep things on lock. DIMENSIONS Necklace: 20" | Pendant: 0.75" x 0.55" x 0.18" I AM UNSURE OF GRAM WEIGHT ON THE GOLD.
