220 Pieces Copper Washers, HELIFOUNER 10 Sizes Copper Metric Sealing Washers, Flat Washers Assortment Kit (M5 M6 M8 M10 M12 M14 M16)

Q: Has anyone used these copper washers in jewelry making? I'd like to know if they oxidize over time.

Uncoated copper will tarnish over time. If there is a film finish keeping air away, it will not unless it is worn off.
