Sharpie Black Retractable Permanent Marker Waterproof and fade resistant permanent marker. This marker is solvent-based, so it is permanent water-based and you can use it, in addition to paper, on many other surfaces such as stone, plastic or metal. You can also use it on more porous and absorbent materials such as wood or fabric, but due to the solvent the ink tends to expand a little. It will also happen to you on very absorbent papers. Ink free of xylene and toluene. Retractable. Contains a 1mm medium tapered tip. Colour: black. Brand: Sharpie.
