Uni Jetstream Standard Ballpoint Pen, 0.5 mm, Black Ink, White Body, 6 pens per Pack (Japan Import) [Komainu-Dou Original Package] by Uni-ball

Perfect pen for writing in small spaces. Pen requirements for my employer: no gel, cannot smudge, smear, bleed through, these are ball point pens so they fit all of the requirements. They are narrow enough that if I need to single line through something for correction all documentation remains legible.

I have finally found my favourite pen! This is a beautiful, fine point pen. It says 0.5mm, but feels even finer, and writes so smoothly. Plus the ink does not smear, even when it gets wet. Definitely 5 stars.

My writing looks much more legible with this pen. Also good for small writing , fitting in a lot more text using the same size area. Very pleased with these pens.

Probably the smoothest writing I’ve ever experienced. Ink flow is consistent - no smudging. Lines are fine and precise - true to size (0.5)

Excellent quality, no bleed, smooth. My new favourite pen for work. I guard them with my life
