Nice beginner set of premiers, though I can clearly see that most of the cores are not centred. I know this can be a problem when they need to be sharpened. The verithins that come in the set are not sharpened, and I'm having trouble not breaking the leads as I sharpen these, even when I use the Prismacolor sharpener. The colour of the premiers lay down very nicely and blend well, and I prefer the look they give compared to my spectrum noirs. I will probably switch to these in the future if they are on for a good price.
