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

It's a bold-line ballpoint pen designed for clear markings and smooth writing. The 1.0mm tip creates visible, crisp lines ideal for corrections, notes, and highlighting. The low-viscosity ink helps maintain a steady flow with quicker drying, and the triangular grip provides comfortable control during longer writing sessions.

Key specs: 1.0mm tip for bold lines, red ink for high visibility, low-viscosity ink for smooth, uninterrupted writing, quick-dry to minimize smearing, triangular barrel for a comfortable grip, and a box of 12 pens (model CE-TRI1-12R).

The triangular barrel shape ergonomically positions fingers to reduce fatigue, offering stable grip and better control for steadier, neater handwriting, especially during long note-taking or grading sessions.

Low-viscosity ink flows smoothly with less resistance, producing fluid lines while drying quickly to reduce smearing and offset on most standard papers commonly used in schools and offices.

Ideal for exams, marking, corrections, margin notes, labeling, and everyday writing in school or office settings where bold, legible marks are helpful.

Remove the cap (or engage the writing mechanism per your model), scribble a few lines on scrap paper to prime the ink, then write normally. Keep the cap on when not in use to prevent drying and store it upright or horizontally away from heat.

Yes. The ink is designed for general use in school and office environments and is typically formulated to be non-toxic for everyday handling. As with all writing instruments, keep away from small children to avoid accidental ingestion.
