A 0.3mm nylon tip delivers the control that detailed permanent marking demands. Sharpie Ultra Fine Point Markers maintain crisp, consistent lines across technical drawings, product labeling, and intricate surface decoration where precision matters more than speed. The hard nylon point resists splaying under pressure, holding its shape through extended use on challenging surfaces.

Alcohol-based ink dries in seconds and bonds permanently to metal, plastic, glass, and wood, surfaces where water-based markers simply bead up. Fade and water resistance ensure marks survive handling, sunlight, and environmental exposure without degrading. Quick-drying formula prevents smudging when working across previously marked areas or when pieces need immediate handling.

Slim barrel design stores efficiently in crowded tool kits and studio drawers, while integrated metal pocket clips keep markers accessible during mobile work. The non-toxic formulation meets safety standards for studio and workshop environments. Whether marking measurements on metal armatures, labeling mixed media components, or adding permanent details to assemblage work, these markers deliver the fine-line control that permanent applications require.
