Genuine Pandora engagement charm.

I got this charm at my bachelorette party or actually the day that I was getting married while we were all getting ready together this was about five years ago I actually never got to use any of the charms they were put up and when I took them out I noticed that they were tarnished so I’m assuming they shouldn’t have been completely sealed I don’t know if these can be just cleaned with the sonic cleaner or if they can be taken to Pandora but it has never been used it’s adorable those are the best pictures that I could get
