Review on 🖊 Versatile Precision Black Micro Pen Fineliner Ink Pens - Waterproof Archival Ink Fine Point Micro Liner, Multiliner - Perfect for Sketching, Anime, Illustration, Technical Drawing, Office Documents & Scrapbooking - 10Pcs/Set by Heather Shaw

Nothing bad to say about her. I bought these to practice my line work and am very satisfied. They don't bleed, black is black, how black can be black. My daughter loves to draw and craft so I bought her another set as she said she loved my set. While the caps don't appear to flow, there are no smudges on the paper (I use a mid-range sketchbook, but I haven't noticed any smudges on ordinary printer paper either). I think they are excellent value for money. The only thing I can't judge is durability/durability. how long the ink lasts and if anything (e.g. bleeding) occurs over time when not in use. Great sentence!
