Pentel of America, Ltd. 100WS pen

Fine-point white marker

The Pentel 100W-S is a permanent marker with a fine fiber tip that delivers opaque white ink on metal, glass, plastic and other nonporous surfaces. It is suited for technicians, crafters and office workers who need visible marks on dark or transparent materials. A snap-fit cap seals the barrel to prevent the quick-drying ink from drying out.

Valve-controlled flow for consistent lines

An internal valve control device regulates ink delivery so the line stays even without flooding or skipping. The fine point suits detail work such as labelling components, marking measurement points or adding highlights to artwork. Sold as a single unit, it slots into a tool pouch or desk organiser without extra accessories.

Replaces messy paint pens and silver markers

This marker upgrades from paint pens that require shaking and silver markers that read poorly on reflective surfaces. The jump is worth it when you need immediate opaque white lines that dry fast and adhere to smooth substrates without smearing. Buyers who need broad coverage or porous-surface writing should look elsewhere.
