I've got to say, when looking about the internet; apart from the obvious places, i.e. the Derwent web site, there is not a lot of reviews or information about the Derwent Studio colored pencils, so I had to purchase them and put them through their paces. I will say this, my mind changed a few times about these pencils whilst reviewing them and actually using them. However, I am sure you are happy to learn that I have finally concluded a decision, a decision I will explain to you in this review.
