These are WATER BASED. I somehow ordered them when looking for alcohol. So disappointed, regardless my review is based on them being WATER Based.
My biggest issue is the colors aren’t true to the cap color. You will have to test on another white sheet before using if you are looking to take advantage of the shades. That inconvenience is why this is 4 stars, to me the set feels cheap because they didn’t take the time to color match ink to cap.
If you like using water to blend, these colors will run fast. I use mine for mixed media, so it’s a bit hard to see but the home brew photo was very lightly nosed and you can see how the edges softened very quickly.
If you blend lots of colors with markers, the tips carry colors for a long time which I dislike, but I can see it as a perk depending on task.
