Uni Pin Fineliner Drawing Pen - Sketching Set of 8-0.1mm / 0.5mm - Black, Dark Gray, Light Gray, and Sepia

Where have these pens been on my life? These are the best fine liners I've ever used.

These are game changers for using with watercolors. It will add subtle lines without being distracting or taking over the rest of the picture, when you use a soft grey or brown... love it

Good product. Poor packaging though.

The various colors are good for fine lining my watercolor art work. I have not experienced any bleeding. It remains distinct on top of the dried watercolors.

I absolutely love these pens for the size of their nibs and they look great when they lay down ink. I also really like the colorsBut the nibs are very delicate. I tend to have a heavy hand a lot of times and that's something I try to be mindful of. But the 0.1 nibs bend easily and don't easily go back to their original straight form.Also, you can't leave a cap off for even a minute without it drying up. I mean DRYING up. If you get it in time you can get it to work again but I struggle with narcolepsy and I fall asleep drawing so I have already had to replace my pens 3 times. I tried everything, soaked the nib in alcohol (which is drying so that wasn't going to work) and then in hot water and nothing, and I even soaked it in Rotring ink.Anyway, I happened to have a Moltow 0.3mm pen that is absolutely amazing and have found their products

Not sure how long they'll last but do that absolutely love these pens. Great color selection for journaling and line work, and having multiple sizes in a single set is really convenient.Most of the pen exteriors are true to color, though the one that looks like umber is actually a true sepia.

I've used a good variety of fineliner pen over the last few decades, and have come to trust Uni Pen's offerings for long lasting consistent performance. They're a fine pick for clean line drawing and multimedia work.

The light greys went dry fast (yes, with the cap always on). I don't know if they were old when sold or if they are just short-lived.The dark greys are lasting longer but I can already see some deterioration.Other than that --- the light grey looks exactly like a 4B pencil, which is exactly what I wanted. The .5 is about the thickness of a Micron 005, and the .1 is about equal to a Micron 003.I will get a light grey Uni-pin from another source and see if they are better than this. If not, I'll try the W&N, Zebra, and Micron greys.
