uni-ball Eye Micro Black Rollerball Pens, Premium 0.5mm Ballpoint Tip for Super Smooth Handwriting, Drawing, Art, Crafts, Colouring, School, Fade and Water Resistant Liquid Uni Super Ink, 12 Pack

Pens are amazing, smooth, and waterproof!

Es de mis bolígrafos preferidos. Me encanta el grosor de la punta y dirá bastante.

I use these pens for writing, bookkeeping, and art projects. They are great!

These are comfortable to use when writing and were bought so that checks are safe if mailed. The ink can not be 'washed' off the check.

i absolutely love these, they write super smooth and don’t bleed!

Although this pen came through with flying colors on all other aspects, I was disappointed with the line width. The description says the pen is a .5 mm nib that creates a .3 mm line, I found the line width to be more like a .7 mm. I don't know how I would measure, but I was able to compare it to other ink lines to come to my conclusion. I was looking for an alternative to pigma micron 01, this unfortunately just doesn't compare as far as line width goes.

These are wonderful pens.... Also, they never skip!

It does the job for the price.
