Cello Tri-Mate Ball Pen, 1.0mm Tip, Low-Viscosity Ink, Triangular Grip, Smooth Bold Lines, Consistent Flow, Ideal for School & Office Use, Black - Box of 12

Key specs: 1.0mm tip for bold lines; low-viscosity ink for smooth writing; quick-drying ink to minimize smudges; ergonomic triangular grip for comfortable handling; black ink; packaged as a box of 12.

The triangular grip provides a more stable and natural hold, reducing finger fatigue during extended writing. It also helps prevent the pen from rolling off your desk when you set it down.

Great for taking notes in school, filling out forms, writing reports at the office, or any daily writing where bold, legible lines are preferred. The quick-drying ink helps when you’re right-handed or left-handed writing on standard paper.

Cap the pen when not in use to prevent drying, store it on a desk or in a pen pouch, and avoid exposing it to extreme heat. When starting after a pause, give a light press to initiate ink flow and write on standard writing paper to prevent skips.

Ink is designed to dry quickly to minimize smudging on common writing paper. Performance can vary with glossy or very smooth surfaces, but on standard paper it should produce clean, legible text with minimal smear.

The 1.0mm version writes with bolder lines, ideal for bold headings and forms, while the 0.7mm option offers a finer line that’s smooth for detailed notes. If you prefer crisper writing, the 0.7mm may suit you; for more pronounced, easy-to-read text, the 1.0mm is often preferable.

The technical performance (ink flow, dryness, and grip) is consistent across color variants; the primary difference is ink color. If you want blue ink, you can consider the 1.0mm blue variant available here: https://fepy.com/product/cello-tri-mate-ball-pen-1-0mm-blue-12

You’ll receive a box containing 12 black Tri-Mate ball pens, each with a 1.0mm tip and triangular grip, designed for easy organization and bulk use in classrooms or offices.

Yes. The quick-drying, low-viscosity ink helps reduce smudging for many left-handed writers, and the bold lines from the 1.0mm tip can enhance legibility for those who angle their writing. The triangular grip also supports a comfortable grip during longer writing sessions.

It combines a bold 1.0mm line with a triangular ergonomic grip, low-viscosity ink for smooth flow, and quick-drying performance, all in a reliable black ink, packaged as a value box of 12. If you’re deciding between variants, consider whether you need a bolder line (1.0mm) or finer line (e.g., 0.7mm) and color choices (black vs. blue).
