The Pilot BeGreen Tecpoint rollerball pen features an extra-fine needlepoint (0.5mm). The stainless tip very smoothly writes a precise line on almost any paper. No skips, no blobs, no bleed-throughs. Ink glides onto the paper without needing to press hard to produce consistent sharp and clean lines. Airplane-safe barrel contains a high percentage of recycled plastic. Refillable.
