Blink - Square Aluminum JPL
Lightweight, easy-care bright aluminum now in square rings for a sleek industrial look without weighing you down. Aluminum will not rust or tarnish. Occasionally (rarely, to be honest) there may be some black ruboff from the metal on your skin, but generally if you give it a good wash in dishwashing liquid and water it'll quit that. And, it's shiny. I love shiny! Closes with a lobster clasp.
