These 8mm jingle bells make a fun element to add to Christmas/holiday themed pieces. They are raw brass and already show patina but for science, I did clean one up (see 3rd photo showing it next to an unaltered one) using a little dawn dish soap and Barkeeper's Friend so if you prefer the brighter gold look, it can be done. They will get patina back over time though. As far as the "jingle", you can hear it but it is a pretty gentle and mild sound. Sold per lot of 20 pieces.
