Its unique acetal plastic casing around the metal ball ensures smooth ink flow, while Uni’s Super Ink offers water, light, and tamper resistance to safeguard your documents. This set includes black, blue, and red pens, designed for ambidextrous use with a sleek, contemporary style perfect for professionals who demand precision and reliability.

## Description

The metal ball of the nib is encased in an acetal plastic, rather than the standard metal surround, which allows for a smoother flow of ink around the ball, and an increased flow as further pressure is applied.

Review: Great Pens - Love these pens I have had a few packs of them and I use them all until they are finished. I write my signature a lot on various forms and fountain pens always seem to smudge so these are prefect. the nib is not fine but not thick and produces a nice write. Very happy. Will continue to purchase.
Review: Better than I imagined - Time and time again I reach out for these pens; they are a delight to write with.
