The SPM-10C Speedmarker is a refillable industrial quality marker which utilizes capillary action to provide a continuous supply of ink to the felt tip. Simply pour ink into the barrel of the marker and the felt packing inside will automatically draw the ink to the felt tip. The speedmarker is the largest of the three refillable markers and is available with a round or chisel felt tip. Universal Type FD marking ink is recommended for marking on both porous & non-porous materials.
