The barrel of a Sharpie marker is molded out of a plastic resin. Screen printing is applied to the Sharpie barrel, including information like the Sharpie logo and the description of the color. A filament made out of a cotton material and used to hold the ink is inserted into the barrel.

How do you make Sharpie?

Pour rubbing alcohol onto a paper towel, then use it to rub off the ink. You can use a gritty hand soap or cleansing cream to do the job, too. One homestyle hint is to dip a cotton ball into milk and swipe over the stain.

What ink is used in Sharpies?

While most washable inks are water based and designed to break down easily, Sharpies use water-insoluble ink that contains Permachrome, a pigment used in ink for ink-jet printers, and xylene and toluene as binding agents to give the ink longevity.
