## Description

Extra Fine Point 0.5mm, Black Ink, 3 pens per Pack

Review: Waterproof once dry. Outstanding pens. - I bought these for urban sketching. I do a pencil sketch, then I finalize my line art with these markers, and then I watercolor over them. They have excellent use for this purpose and work fantastically. The ink is very solid and opaque, the lines are reliable, and these are awesome pens. They don't feather they don't bleed they don't go through paper unless it's extremely thin, and I'm very happy with this purchase. I would highly recommend any of the super ink pens by uni. I have some uni ball pens that I bought at the end of the 90s and in the early 2000s, and they still write like champs if I haven't used them for a while. There's lots of ink in them and they work a long time. I have to say I've never had a product from this company that I was disappointed in. They're white gel markers are the best on the market. If you like gelly rolls, you were going to love their white gel pens. They're even more noticeably opaque and the ink goes on excellently..
Review: Perfect for water coloring sketches - Bought these for ink sketches prior to water coloring and they work great!
