The Magnetic Ball Marker comes in two different varieties- dome and die struck.  The dome is an epoxy coating that shows great detail of any artwork.  The die struck version is good for those less intricate logos.

Besides being used as a marker that adheres to the tab of the glove, they can also be used on hat clips, divot tools, or any other tool that is magnetic.  Markers are sold individually as well as with the gloves.

Turnaround time for domed is 1 week.
Turnaround time for die-struck is 1 month.
