Big E 5/5

Exactly the desk pen I need

I use lots of pens at work and these have become reliable. I prefer a 0.7mm medium for everyday forms, but these lines stay dark and clean. Retractable is handy, and the uni Super Ink gives extra confidence for signed documents.

Love the 1.0mm feel

Really enjoy the thicker 1.0mm line — it writes so smoothly and feels substantial in hand.
Ellen Perduyn 5/5

My students really like them

I teach creative writing to vets and leave pens available — they consistently reach for these. The medium-to-bold gel glides smoothly and makes writing feel easier, even for those with shakier handwriting.
Kindle Customer 5/5

Ink stands up to rain and spills

I write many letters and cards; the ink hasn’t run when wet. Past brands blurred in the rain, but these hold up and remain legible.
LINNIE 5/5

Daily journal staple

These are my go-to for journaling. The grip is comfortable, ink flows consistently without skipping, and the 0.7mm/medium option gives a tidy, medium-width line. A 12-pack keeps me stocked.
M. E. Boyer 5/5

Great for finer work

If you need a finer, precise line this pen performs smoothly with minimal smearing. Works well for checks and detail writing.

Good while they lasted

Initially very smooth and deep black — great for lefties. After about four months some began to skip a lot. Still recommend for the quality while new, but expect they’ll eventually run down.

Excelente producto.
Kevin Cross 5/5

Security-minded and comfortable

Bought for safer check writing because the pigment bonds with paper. A few pens had a crusty tip that wiped off easily, after which they wrote smoothly. Ergonomic feel and solid lines — good for fraud protection.
tonymita 5/5

Beautiful, consistent flow

Excellent pens with a lovely, steady ink flow that makes writing feel effortless.
Mayo 5/5

Thin, crisp lines and reliable

These produce very fine, crisp strokes good for small writing and detailed sketches. They don’t smear or bleed and have a comfortable grip and satisfying click.
Kristal 5/5

Smooth writer, minor smudging if rushed

Looks and feels great; lasts for weeks with everyday use. Very few break, but let the ink dry a moment or it can smudge.
Diana Ma 5/5
