These implements dispense a controlled flow of pigmented liquid through a durable metal point. The robust tip facilitates application on diverse surfaces, including metal, plastic, and glass. For instance, they are employed to mark industrial components, create signage, or execute detailed artwork.
The resilience and precision afforded by the applicator make them valuable in environments where permanence and legibility are critical. Historically, these tools have offered a reliable alternative to brushes and other less durable marking methods, offering enhanced control and minimizing mess. Their utility spans from heavy industrial applications to artistic endeavors, providing a consistent and lasting mark.
