The Sharpie® Twin Tip Permanent Marker combines two versatile marking options in one convenient tool. Use the fine tip for smooth, detailed lines and the ultra-fine tip for precision writing and tight spaces. Its permanent black ink creates bold, consistent marks on most surfaces, while waterproof ink helps resist smearing and fading for long-lasting results. Made in the USA with globally sourced components, this marker features AP Certified, non-toxic ink and is ideal for offices, schools, creative projects, workshops, and promotional giveaways.
