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.

You'll never need anything else... one love.
This marker is hand-stamped, welded then hand-polished one one side, the other left raw... finally we filled it with translucent sea bubble blue, blue skies blue, titanium blue, and white paint to pop it like it's hot.
