Adult Coloring Book Spiral Bound for Women, Thick Paper Coloring Book for Alcohol Markers (30 Girl's Gram Designs)

I like the Mindful Palette coloring books. I've had zero issues with bleedthrough even when applying multiple layers. https://www.amazon.com/Coloring-Spiral-Alcohol-Markers-Designs/dp/B0F4QWVTMK?ref_=ast_sto_dp Ohuhu also has a set of coloring books. I think they're called Simple Pleasures. There were two available on the Ohuhu website, but I got a set of four on Amazon. The designs aren't necessarily my favorite style, but again zero bleedthrough even with them being double-sided.
