Since turning their focus to markers 50 years ago Sharpie have produced markers for a range of uses. The Sharpie Professional is a permanent marker that apparently lasts 50% longer than standard Sharpies.
I have a Sharpie Professional Marker in black. The grey plastic barrel has yellow rubberised inserts which make for a non slip grip & the oval shaped design of the cap & barrel mean they won’t roll of working surfaces. There are 3 small raised squares positioned either side of the cap. These are in line with the yellow rubber section & make it easy to remove the cap if wearing gloves.
