I have a 24 set of Derwent watercolor pencils, but was wanting to find a larger set, without spending a small fortune. When I found this listing for a 72 set by Castle Arts, that was under $40, I was really excited, but apprehensive about how good the quality would be. I read through the reviews, and decided to just give them a chance. And I am glad that I did. These are a nice affordable set, without losing out on quality.Not only did this set have a very nice selection of colors, with several light to dark shades of each color. But the leads lay down very smooth and creamy, which is something I look for in pencils I use. The lead is not as soft as other watercolor pencil brands I’ve tried. These leads are more firm, like regular colored pencil lead. I assume that they have more binder in them than other brands do, but this isn’t a flaw for me. They can reach a deep vibrant opacity, with very little pressure needed.I tested them both wet and dry, and am very pleased with both methods. These pencils can be used in several light layers, using the wet technique, or can have a rich vibrant result if used dry. Definitely a very versatile product. So far, I love these pencils. The company was very friendly, and prompt with delivery.Very pleased with my purchase.
