Coca-Cola Coca-Cola Metal Beads? Charm Parts Material I think these are from 20-30 years ago. They are small. I don't know what parts they are. I think they are made of metal, but I apologize if I'm wrong. There is rust? Stains and scratches. The Coca-Cola lettering has an embossed-like, slightly uneven texture. Weight of one: Approximately 3-4g Please note that there may be some error. Shipping via Rakuraku Mercari Ne-ko-posu (domestic Japanese shipping service) Please refrain from purchasing if you are nervous about home storage.
