A permanent marker is a type of writing instrument that uses a special ink designed to be long-lasting and resistant to fading. The ink is typically made from dyes and solvents, allowing it to adhere to various surfaces, including paper, plastic, metal, and wood. Permanent markers are commonly used for labeling, crafting, and art projects due to their bold colors and durability. These markers come in various tip sizes, from fine to broad, enabling precise or broad strokes depending on the task. Unlike regular markers, the ink in permanent markers is waterproof and dries quickly, making them suitable for both indoor and outdoor use.
