Product Summary:

• Design: Features a long, slim vertical bar pendant (also known as a "stick" or "cuboid" locket) with a clean, polished finish.
• Material: Usually crafted from 925 sterling silver with rhodium-plating for a tarnish-resistant shine and extra durability.
• Chain: Suspended from a traditional silver box chain, which consists of square links that provide a geometric, modern profile.
