Hotel Napoleon Paris Key Chain. Heavy Brass Fob with Chain Link Connector. Fob is about 2 1/4 Inches in Diameter and about 1/4 Inch Thick. Raised Design on Front, Hotel Information on Back. Comes with a Key...think it will still work? The Key is held by the last connector link. I don't think it can be removed with anything short of a metal cutter. I also don't think that a new key can be added without installing some sort of connector device. Thanks to a sharp eyed viewer for noticing this. A Wonderful Souvenir of a Marvelous City.
