SAKURA Pigma Micron Fineliner Pens - Archival Black Ink Pens - Pens for Writing, Drawing, or Journaling - Black Ink - 01 Point Size - 6 Pack

I use these to add an outline to my watercolors. They are waterproof, and the line is very fine. Since Im just learning, they clean up my work and make it look more professional - something thats harder to do with a detail brush.

My husband will only use this pen for his bible notating.

These pens are great. Waterproof, thin line, etc. the only problem is that if you use them often, it can get a little too pricey to replenish your stock, which is why I gave it 4 stars.

This It has a beautiful point but runs out of ink very quickly! While using it it seems to flow very nicely until it doesn’t.

some of the pens leaked,the ones that didnt leak were dried up

Very smooth

These pens are the absolute best for fine detail. (Mine are the 01, .25MM pens and they work well on my mixed media paper when doing my Neurographica art projects and on fabric. I heat set the ink on fabric so it can be washed and is permanent. I also have the multi color set and they all work great too. If you do get these pens, it is suggested that you store them on their side, laying flat.

The ink did not flow uniformly.

Dried out in less than 30 minutes of drawing!!

I havent experienced the same issue as the other commenter about the ink running out fast. I am a huge fan of these pens for their accuracy and quality of ink (hasnt ever run etc.). My only criticism is, and I am somewhat of a unique user, the ink can sometimes run inside the cap. Im not a desk user, I carry these around in my pockets on construction sites. Occasionally I have noticed (and this isnt consistent) some of the pens will leak inside the cap, and when you remove the top you will notice this. The cap seals completely, so it has never ruined anything, but beware if you are rough and tumble with them, like I.
