Zippo Key Chain. A Metal Fob with Detachable Double Rings. Each Ring Pulls Out to accept a Key, Then pushes back in to lock. Fob has been Personalized with Neuber and a Diamond in Blue on Front. Back is Blank. I believe this was from Neuber Industrial Diamonds Inc out of Massachusetts. Unsure of Vintage and Metal. Comes in Original Box that is still in pretty decent shape.
