Please see all of the photos as these serve as part of the description.
The Charms are non-magnetic. I think these may be made from Pewter, but not 100% sure.
The bracelet is a magnetic base metal.
Some of the Charms are marked, but I can't identify the brand based on the mark. Please see the photos for the mark.
