## Description

Uni-ball StyleFit Retractable Gel Ink Pen (UMN-139-28), Slim & Stylish Body, 0.28 mm, 16 Color Set

Review: These write beautifully, and I love the array of colours!!! It's so nice to finally find a .28 nib! Please make more!!! In metallic would be sweet!
Review: These are wonderfully color dense and not scratchy despite being very very fine line pens. There's no clip on them and they're VERY slim pens, so using them with the elastic loop in my planners is problematic. I keep them in a pencil case. These are very high quality very fine line ballpoints with good and saturated colored ink. useful and fun. They have not dried out or hard-started in months of use (a perennial problem with other fine line pens in my experience). Really good value for money.

*by A***! on 24 April 2024*

I bus 1 hour to school. Bought to reduce the size and weight of my backpack. It's worth it. Pens write so smooth, bright colour. Barrel is thin at first and still an careful when using. The price is a bit high but, the advantage of carrying so many without bulk or weight.... It's does offset that.
