Ultra-fine violet color, 0.4 mm tip, gel ink with stable output, quick-set ink to reduce smearing, needle-point control for accuracy, and refill compatibility with BLS-GC4 refills; comes as a pack of 12.

Yes, it is refill-compatible. Use BLS-GC4 refills to extend your pen’s life and keep writing with the same mechanism and feel.

It's excellent for school notes, detailed headings, fine diagrams, card making, and any project that benefits from crisp, narrow lines and smooth gel ink.

Allow a moment for the ink to set after writing, apply light, steady pressure, and let areas dry before stacking or handling; the quick-set ink helps reduce smear during fast note-taking.

The gel ink is non-toxic and designed for everyday writing, making it suitable for general classroom and office use.

This violet 0.4 mm pack is one color option. Other colors in the G-Tec-C4 line (such as blue and black) are available on Fepy, offering similar 0.4 mm precision with different ink colors.

Unscrew or separate the pen barrel, remove the used refill, insert a new BLS-GC4 refill, and reassemble. Then test on scrap paper to confirm ink flow and line quality.

A 0.4 mm tip creates very fine, precise lines suitable for detailed work. Higher sizes like 0.5–0.7 mm produce bolder lines and are better for emphasis or larger lettering.

Yes. The pack of 12 provides better per-pen value and ensures you have plenty of ink for long-term projects, with the option to reuse via compatible refills.
