I love Castle Art products. The quality is excellent, and so is their customer service. I have at least 6 different sets of their products, from Watercolor tubes, Watercolor 120 Pencil set in zip case, Watercolor pen set, Colored pencils, and Graphite sketch sets, and 9x12 sketch pads. Everything is perfect. Their Customer Service Team is absolutely top knotch. I am so pleased.
