Pentel PEN100W Broad Felt Tip Marker Opaque White Ink

Product Description

The PENTEL PEN100W is a broad felt tip marker loaded with opaque, permanent white ink designed for marking on metal, glass, plastic, and most nonporous surfaces. It delivers clearly visible white lines on dark or hard-to-mark backgrounds where standard markers fall short. A snap-fit cap seals the tip to prevent dryout during storage, and an internal valve control device regulates ink flow for consistent line quality across the full life of the marker. The special fiber tip provides controlled application without feathering or skipping. Quick-drying ink resists smearing once applied. Suitable for trade professionals marking pipe, conduit, sheet metal, glass panels, and similar materials in the field or shop.

The PEN100W is used in HVAC, plumbing, electrical, and general construction trades wherever permanent, legible marks are needed on dark or nonporous materials. Common applications include marking cut lines on black ABS pipe, labeling metal conduit runs, marking tempered glass, and identifying components on powder-coated equipment. The broad tip lays down a bold line that stays readable under shop conditions. One marker per unit; suitable for individual technician use or as part of a service van kit.
