These work really well with my Ohuhu and other alcohol based markers, and I really like them. They dry quicker than other fine liners I’ve tried, and don’t smear as much as others I’ve had. I was easily able to erase the pencil lines after doing my lineart. I chose this D&D character to test if they’d bleed into my yellow like some of my other fine liners did, and I think it’s quite clear if it did happen, it’s very not noticeable! I’m very happy with these fine liners. The amount of sizes and shapes you get in the pack is very good for the price too. I’ll probably be purchasing this set again.
