Pilot G-TEC-C Rollerball Pen, 0.3 mm Needle-Point, Ultra-Fine Lines, Clean Micro-Text, Ideal for Technical Notes & Journals - Black

The 0.3 mm tip creates crisp, compact black lines that stay legible on grids, tables, and narrow margins, making micro-lettering and detailed labeling much easier.

Ultra-fine 0.3 mm tip, needle-point control for precise ruling on grids, regulated ink feed for smooth, steady flow across long pages, fast-setting ink to reduce smudges, and a slim barrel designed for steady micro-writing.

Architectural notes, mathematical formulas, dense journaling, technical diagrams, fine-chart labeling, and any task requiring tight, clean lines and high precision.

Cap the pen when not in use, apply steady pressure for consistent ink flow, replace the refill when the line starts to fade, and wipe the nib gently if it accumulates ink residue to prevent transfer.

Pilot inks are formulated for safe office and school use and are designed to be non-toxic and suitable for writing on standard paper, with safety testing typical for writing instruments.

The G-TEC-C 0.3 mm offers ultra-fine, precise lines with a regulated feed for smooth output. For slightly broader lines, the Pilot G-TEC-C4 0.4 mm option provides a noticeable difference in line width, while still preserving smooth ink flow.
