A place to put your ball marker so it doesn't dissappear. I was tired of loosing my ball marker, so I designed a holder for it, for my Superstroke grip. It fits in the hex hole on top of the grip.
It can take a marker up to 26mm and has a hole for 6x1 mm magnet to secure the the marker. I has a part cut out for easy access to the marker.
