The price for these at $20/12 markers was unbeatable. I've used Prismacolor markers in the past and had them all stolen by my students. They obviously liked them, as well! The colors are bright and they don't leave streaks. They do an incredible job coloring illustrations, creating a bright, smooth, solid space. The broad tip is breat for coloring in large areas and the small too is great for outlining or detailing. If you weigh these against Sharpies, there is no comparison. These are far, far superior. Invest a little extra money and get these instead. It's worth it!
