Precision labeling tool

The Sharpie 37121DZ is a pen-style permanent marker with an ultra-fine narrowed tip for extreme control. Alcohol-based ink dries quickly and resists fading and water on most hard-to-mark surfaces. Each pack contains twelve black markers certified AP nontoxic. Ideal for detailed identification and labeling tasks.

Replaces broader tips

Switch from standard fine or chisel points when you need to write in tight spaces or on small components. The ultra-fine point style allows precise markings that broader tips cannot achieve. The jump is worth it for circuit-board labeling, scale models or any surface where line width must stay minimal.

Immediate use, cap discipline

Remove the cap and write; no setup or drivers are required. The quick-drying alcohol ink reduces smudging but can dry in the tip if left uncapped. Store horizontally with caps firmly snapped to maintain flow across all twelve markers.

Questions about this item

What surface preparation does the ultra-fine point marker need for permanent adhesion on hard-to-mark materials?

The alcohol-based ink marks permanently on most hard-to-mark surfaces without special preparation; ensure the area is clean and dry for best results.

How should the pen-style markers be stored to prevent the narrowed tip from drying out between uses?

Store each marker horizontally with the cap snapped firmly shut; the quick-drying alcohol ink will stay ready for the next labelling task.

When will the AP-certified non-toxic ink need replacement in a high-volume labelling workflow?

Each of the 12 markers delivers permanent, fade-resistant marks until the ink is depleted; replace individual pens as the ultra-fine line begins to fade.
