I opted for this and other fabrics have not been disappointed. The colors are very strong, they do not smell unpleasant and can be easily washed out of your fingers. All this was important to me. But you should be sure to set a cardboard or similar underneath the fabric so the color is not suppressed. Very good I also like that the colors can even mix. I have drawn on clouds, I painted with the blue pen with the white pen contours - after drying the effect was really really great. I would order these pens at any time.
