Sharpie Extreme markers have the same fine point as original Sharpies, but also feature a specially formulated ink that stays extremely permanent in even the toughest conditions.

The high-contrast ink resists harsh UV light, as well as rainy, snowy, and muddy environments. Great for use on outdoor equipment for sports, camping, playgrounds, etc. Bold color marks can be made on most surfaces- including plastic, glass, wood, and more!
