When these came in the mail I tested these out in my new sketchbook that had drawing and mixed media pages in it. I was worried because they weren't expensive. But It worked beautifully on the mixed media and the colors looked gorgeous. 100% honesty. If I didn't believe it worked I wouldn't be saying it. I'm so glad I bought these. Brush and water is a must have with these as it really helps with the watercolor effect ❤️
