.160 Marker [Empty]
Save some money and make your own OTR markers. The 160 OTR empty pocket marker is the shorter version of the .060 jumbo paint marker. This marker features a pump action valve with a chisel tip nib that is replaceable. Fill with your favorite color ink. This will work best with dye based ink or most alcohol or water based ink so long as its thin enough to flow through the nib.
