Avery Marks-a-Lot permanent markers are perfect for any project you may have and will never fade! Our markers are permanent on nearly every surface, including cardboard, wood, metal, plastic, PVC, and more! The water and fade resistant ink make them ideal for both indoor and outdoor projects, especially signs and banners for parties and garage or yard sales. Unlike fine point markers, the chiseled tip on our markers allows you to control how wide or thin to make each line. Our markers are best for writing clear writing as you don't have to wait for the ink to dry and you never have to worry about smearing the ink, unlike with most paint markers! Unlike with fine point markers, the strong chisel tip on our markers allows you to control how wide or thin each line is. The desk-style markers are great additions for any office or crafting kit. The low odor non-toxic ink means these markers are safe for not just adults but also kids and can be used in classrooms. The bold edges and ink create clear, precise lines that can be seen from afar, making them perfect for posters and presentations in the classroom and conference room. Purchasing this bulk set of 12 will allow you to have a marker for your desk, children, craft room, and wherever else you may need one!
