I have kept this unused for a long time. There is some clouding due to aging. The material is brass. The bell rings. As this is a vintage item, there are some black spots, etc. Please understand that this is a long-term storage item and an antique item. Diameter: Approximately 1.3cm Simple packaging. I will put them together in one bag and ship them. I am also selling other parts. I will give a discount for combined purchases! Thank you for viewing.
