※ Because this item is also listed on other sites, it may be removed from sale. m(_ _)m I received this about 10 years ago from someone who worked at Franck Muller. I had stored it away with a few business cards inside. The material is unknown, but there are small areas where the surface is peeling, either from the beginning or due to aging. (Photos 6, 7, 10) The string also has a bend in it. I think it's a novelty item. I'm listing it because someone might like it.
