Pilot G-Tec-C4 Rollerball Pen, Gel Ink, Ultra-Fine 0.4 mm Tip, Smooth Ink Flow, Clear Writing, Comfortable Grip, Ideal for School & Office Use, Black – Pack of 12

It uses a 0.4 mm micro-fine tip with gel ink. The bio-polymer gel formula promotes consistent ink flow and clean lines, with smudge-aware drying to help keep notes neat.

Key specs: 0.4 mm micro-fine tip for precise lines; consistent gel flow with a bio-polymer formula; smudge-aware drying to reduce smears; needle-point control for accurate writing; refillable with BLS-GC4 refills to extend pen life.

To extend life, replace the ink cartridge with a BLS-GC4 refill. Unscrew the barrel, remove the spent refill, insert the BLS-GC4 refill, and screw the barrel back together. This keeps your writing consistent and cost-effective.

Ideal for forms, technical drawings, precise note-taking, exams, and everyday writing in school, at the office, or at home where crisp micro-lines and reliable ink flow are important.

Cap the pen when not in use, use a light touch, and allow a moment after writing for the ink to dry. The gel formula is designed for relatively fast drying to help keep writing neat on most papers.

Yes. The G-Tec-C4 uses standard gel ink designed for everyday writing and forms. It is non-toxic and suitable for school and office environments, with safety-conscious design typical of Pilot products.

Compared to other fine-tip gel pens on Fepy, the G-Tec-C4 offers a 0.4 mm tip for ultra-fine lines and a refillable BLS-GC4 system. For users who want even finer writing, you might consider the Pilot G-Tec-C3 (0.3 mm) or for slightly bolder lines, the G-Tec-C5 (0.5 mm).

Tip size affects line width and perception of ink density. A 0.3 mm tip (C3) yields finer lines, good for tiny text and detailed drawings. A 0.4 mm tip (C4) provides a balance of precision and readability for forms and handwriting. A 0.5 mm tip (C5) creates slightly bolder lines, which can be easier to see on printed forms or in presentations. Choose based on your writing style and the document type you’re working with.

The 12-pack offers consistent, high-quality gel ink with a precise 0.4 mm tip at a per-pen cost that’s favorable for frequent writers. Refills extend the life of each pen, improving long-term value and reducing replacement frequency.

Hold the pen with a relaxed grip and let the 0.4 mm tip guide your writing. Use short, controlled strokes for precise lines, especially when filling forms or sketching fine details. Keep the cap on when not in use to preserve ink flow.

If ink skips, try a gentle scribble on scrap paper to start the flow, then resume writing. If the ink appears dry, store the pen with the cap on and, if needed, replace the refill with a fresh BLS-GC4 to restore smooth writing.
