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

Key specs: blue ink, 1.0 mm ballpoint tip, low-viscosity ink for steady flow, fast-set ink to reduce smears, triangular barrel for ergonomic grip, and a box containing 12 pens.

The triangular barrel provides a more natural, stable grip that reduces slipping and distributes pressure more evenly across your fingers, helping you write comfortably for longer without hand fatigue.

Ideal for schoolwork, office forms and documents, labeling, and everyday writing tasks where bold, clear lines are beneficial. The 12-pack is convenient for personal use or small teams.

Cap the pen when not in use to prevent the ink from drying. Use the tip to write, and store pens in a cool, dry place. If a pen skips, gently scribble on a scrap sheet to prime the ball before continuing to write.

Yes. The ink is designed for everyday educational and workplace use and is formulated to be non-toxic and suitable for typical school and office settings (subject to standard safety guidelines).

Compared to other blue 1.0 mm pens on Fepy, the Tri-Mate 12-pack offers reliable, consistent flow and a comfortable triangular grip with a value-packed 12-count box.

If you want bolder lines and easier readability for headings or forms, 1.0 mm is a solid choice. For finer writing and more precise work, a 0.7 mm option would be better.

A 12-pack provides consistent supply for multiple users or longer periods, reduces the frequency of reordering, and often offers better per-pen value compared with buying singles.

Absolutely. The bold 1.0 mm line stands out on forms and labels, making handwritten entries easier to read and less prone to fading in busy documents.

Low-viscosity ink improves flow between the ball and the paper, reducing skips and producing a smooth, continuous line. This helps deliver consistent performance across long writing sessions.
