These watercolor markers are awesome! I love coloring in the adult coloring books & I was looking for something else to use besides the mundane use of colored pencils or regular markers. These were perfect! They take a little getting used to, but they are so much fun to use! They are totally worth every penny! My step-son has confiscated them from me to use on his own little art projects. I think I am going to have to get him his own set now lol.
