Review on 🖋️ MUJINHUA Black Micro-Pen Fineliner Ink Pens - Waterproof Archival Ink, Micro Fine Point - Ideal for Artist Illustration, Sketching, Technical Drawing, Anime, Comic, Manga, and Bullet Journaling (Fine Point) by Kim Sanchez

I am very disappointed in these pens. The listing says "waterproof" and "archival" but the pigment sticks I received clearly say "water-based" and "waterproof" on the page. They've worked well so far, but I bought them specifically to use with my Ranger Archival Ink, which doesn't bleed when using a water-based product to seal. I worked hard on the background and then sealed it with a glossy water based sealer. Imagine my dismay when the brush started smudging the pens with archival ink. My archive stamp color was fine. I just re-read the list and nowhere does it say these are water based ink pens. It says they're archived, but it's not. The seller must amend the ad to state the facts. I resent having spent money on something I don't need. My husband threw away the packaging otherwise I would have sent it back. If you want waterproof ink pens, this isn't it!
