This listing is for beautiful brass discs. These discs are used for jewelry making and are great for engraving, etching, hand stamping, hammering or even as a grounding plug. The edges need light finishing. We now offer thicker discs than 14 gauge. You will be surprised by the solid brass discs in 8 gauge. These are beautiful and are commonly used as golf ball markers, but also make a great dog tag for a large dog. They are super sturdy and if you prefer, come with an 1/8" hole predrilled.
