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

Tip size: 0.4 mm (ultra-fine); Ink color: brown; Ink type: gel with bio-polymer formulation; Dry time: fast-drying; Tip: needle-point precision; Refill compatibility: accepts BLS-GC4 refills; Pack: 12 pens.

The 0.4 mm tip delivers crisp, precise lines ideal for headings, diagrams, fine handwriting, and detailed labeling. It minimizes feathering and produces clean gel lines suitable for neat presentations and crafts.

To refill: twist the pen to separate the barrel sections, remove the spent refill, insert a new BLS-GC4 refill with the correct orientation, then reassemble the pen. Press to start writing and recap when not in use to prevent drying.

It's great for school notes, precise headings, small diagrams, labeling in projects, and card making where fine, clean brown lines add detail and contrast.

Smooth printer paper, sketching paper, and light-weight cardstock usually perform well. The gel ink resists feathering on these surfaces, while heavier papers help prevent show-through in multi-page notes.

Yes. The ink is a non-toxic gel formulation designed for safe, everyday use in classrooms and home offices, with a low-odor profile suitable for prolonged writing sessions.

Let the line dry for a moment after writing, cap the pen when not in use, and use it on appropriate paper surfaces. The bio-polymer gel ink is formulated to set quickly to minimize smudges.

The 12-pack offers cost-per-pen savings, ensures a ready supply for ongoing projects, and provides consistent color and performance across multiple uses—ideal for students, teachers, and crafters working with brown detail lines.

Compared to color-varied G-Tec-C4 options, the brown 0.4 mm variant provides a specific tonal detail for contrast-heavy work.

Hold it like a pencil for control, apply light steady pressure for consistent lines, and practice your strokes on scrap paper to get a feel for the 0.4 mm tip. Refill promptly when the ink lags to maintain smooth writing.

The pen uses non-toxic gel ink and is designed for everyday use in schools and offices. As with all writing instruments, avoid chewing the pen tip and keep out of reach of small children to prevent choking hazards.
