  • Copper/brass will tarnish/patina over time and after use. Colours will change and appear over time giving the metal even more character. Ball markers can be polished using a cloth and a jewellery cleaner or Brasso.


    We use the highest quality metals to create our products. We do our best to ensure that all materials use are pure and free from scratches or dents but brass and copper are soft metals so this isn't always possible.
