Also if you're having issues with sharpening, Id actually recommend getting the prismacolor sharpener that they sell on Amazon. The only weird thing is that you have to rotate the sharpener itself and keep the pencil still instead as some of the reviewers suggests, but otherwise it's magnitudes better than the previous sharpeners I used for color pencils since they always broke the tip.
