Go bold with Sharpie M15 Permanent Markers, specifically designed to be used on most surfaces for long-lasting durability. The robust bullet tip with bonded nib lays down broad lines, ensuring a rich colour application, and can endure repeated pressure and daily usage. These markers also feature fade and water-resistant ink that dries quickly to avoid unwanted smearing, while the reflow ink system prevents the ink from drying out if left uncapped for up to 10 days.
