Key Features & Benefits
-
Pressurized Ink Technology: Operates under constant internal pressure to eliminate air pockets, ink starvation, and skipping during high-acceleration toolhead direction changes.
-
Zero Dry-Out Reliability: Won't dry out even if left idle on the plotter arm for extended periods, reducing prep time and material waste on start-ups.
-
Universal Industrial Media Compatibility: Writes smoothly on a wide variety of materials including standard marker paper, vellum, heavy oak tag, plastic film, synthetic textiles, and treated leather.
-
High-Contrast Ink Formula: Formulated with an ultra-opaque, fast-drying black ink that creates crisp, high-visibility lines for automated optical cutters and manual drafting inspection.
-
Durable Metal Housing: Built with tight-tolerance machining to reduce toolhead vibration, maintain consistent line widths, and extend the operating life of your CAD/CAM equipment.

happy with pens
We had been purchasing the Fisher Plotter Pens from another distributor, and were apparently being charged LIST PRICE. RFSUPPLY.COM price was deeply discounted on the same pens, saving us greatly, as we use 24 pens (1 box) every two months!
