ARTEZA Acrylic Paint Markers, Set of 20

I was set to give these a glowing review at first, I got the package and immediately started playing with them, of course. Doodled on some paper with them to test the colors and whatnot. Put the box on my craft table to come back and actually use on the intended project. When I got back to them a few days later and started my mandala the first round was great, next day I came back to work some more and it was like the tips were clogged and not flowering the paint paint smoothly anymore. It completely ruined my painting, never been so disappointed in a product before. All within a week, from believer to heartbroken fan.
