When the laser cutter can't make it's way through material this thick, we had to bust out the water jet!  Double the thickness of our normal markers, this baby has heft.  1.25" in diameter. 
This ball marker is hand stamped with "Rub for Luck" on one side with Ow&Co. surrounded by diamonds on the other.  We then hand-buffed for a stunning polished finish and finished off with a touch of translucent blue paint.
