Watercolor coloring books are a thing I recently learned about! They're printed on thick watercolor paper, so you can use washes and wet on wet without tearing up the paper or having it buckle. I've got this one and I love it https://www.amazon.com/dp/B01M0JXDRZ/
I bought this one on Amazon, and I really like it. It doesn't really bleed, but I always put a piece of printer paper underneath just in case. I use it to practice coloring techniques before coloring in my own artwork : )
Thanks:)))
I used Camlin Kokuyo Student Watercolors and Navneet 200 gsm Cold Pressed papers (Discontinued a long time ago!)
And Yeah, I'm looking to upgrade from these! It's easier to paint with artist grade colors and papers.
