Inspired by Bryson DeChambeau’s revolutionary approach to the game of golf, we’ve created a ball marker for the physics and maths fans.

This double sided marker features a finely detailed compass on one side and some helpful maths equations on the reverse.

Hand crafted from solid brass and precision laser etched before an antique finish is applied.

This high quality commemorative coin has very intricate details and fully embossed pattern on both sides. Diameter 35mm, thickness: 3mm.
