Uni-ball Zento Fine Rollerball Pen, 0.7 mm, Water-Based, Ultra-Smooth, Comfortable Grip, Ideal for Everyday Writing, Lavender Barrel / Blue Ink – Pack of 12

0.7 mm line width, water-based ink for easy gliding, low-friction feed for steady flow, comfortable balanced barrel, purple-lavender color on the outside, blue ink color, sold as a pack of 12.

The 12-pack contains twelve Uni-ball Zento fine rollerball pens with blue ink and lavender barrels. Each pen is a complete writing instrument; no extra accessories are included.

The ink is designed to glide smoothly with minimal resistance, reducing hand fatigue and enabling clean, effortless strokes even during longer writing sessions.

It writes well on standard office paper, notebooks, and most everyday writing surfaces. For best readability, test on a sample page if you’re using glossy or coated paper.

Great for journaling, taking notes at work or school, drafting letters, making lists, and everyday handwriting tasks where smooth ink flow and legible lines matter.

Hold the pen with a relaxed grip at about a 40–60 degree angle to the page. Apply light pressure to produce a clean 0.7 mm line; pressing harder can cause thicker lines and potential feathering on some papers.

Yes. The ink is non-toxic and designed for general writing use in offices, schools, and homes. It is suitable for everyday writing tasks and typical classroom or office environments.

This pen is designed as a complete writing instrument. It is typically sold as a disposable rollerball pen rather than a refillable cartridge model, so you would replace the pen when the ink runs out.

Buying a 12-pack often provides a lower per-pen cost and ensures you have multiple pens on hand for daily use, reducing the need to reorder frequently. It’s a convenient option for offices, schools, or households with heavy handwriting needs.

Store upright or horizontally in a cool, dry place away from direct sunlight. Keep the tips capped if they are cap-retractable, and avoid exposure to extreme temperatures to preserve ink performance and longevity.

Zento uses a water-based rollerball with a smooth, low-friction glide, while Signo gel pens use a gel ink that can feel slightly thicker and may have different drying times. Signo gel pens are often favored for bold lines and vibrant gels, whereas Zento emphasizes ultra-smooth writing with quick, clean lines on everyday paper.

Jetstream is typically a fast-drying, low-odor ballpoint with a different ink chemistry (oil-based) and a slightly crisper feel, while Zento uses a water-based rollerball for a smoother glide and more fluid line. Jetstream may dry faster on glossy surfaces, whereas Zento offers a softer, more fluid writing experience on standard paper. See also: https://fepy.com/product/uniball-jetstream-0-7mm-ballpoint-pen
