Permanent Marker Black

For fast, affordable customization, using a Magnum permanent marker on blank yard signs is a reliable solution for businesses, real estate agents, political campaigns, and event organizers. Magnum markers are designed with ultra-bold tips and fade-resistant ink, making them perfect for writing clear, visible messages on 4mm corrugated plastic signs. Their high ink flow ensures smooth, consistent coverage, while the quick-drying formula resists smudging - even in outdoor environments. Whether you’re updating signs on the fly or creating one-of-a-kind messages, Magnum markers offer a simple and professional way to make your yard signs stand out without the need for printing or vinyl lettering.
