Review on 🖊️ Precise Micro-Line Pens, Black Waterproof Fineliner Ink Pens with Archival Ink - Ideal for Artists, Illustration, Sketching, Technical Drawing, Manga, Office Documents, and Scrapbooking. Comes in 9 Sizes, All in Black. by Sasha Hsiao

I deducted 2 stars because the product claims to be waterproof which is a lie. I used water based markers to draw with and the ink was reactivated and mixed with the color of the marker ink giving it a greyish, washed out appearance. They are not waterproof if water smudges them. That being said, if you don't care if they're waterproof or don't plan on using water-based carriers over them, then they're fine. Good price for a starter set. At least they have different spring sizes for practice. (Small detail: the smallest pen size stopped working for me. I'm not sure if it ran out of ink that quickly, but I have this problem a lot, even with top brands like Sakura and Copic. I just thought I Mention it here, who cares, but didn't bother me as they were relatively cheap)
