Oops! Sorry, didn't mean to give bad advice. I guess I was thinking more of just "straight" usage, rather than blending. The Prismacolors definitely are softer.Originally posted by DVCajun
A friend of mine had the EK Success pencils and I tried the blender pen on them-- it didn't work very well. As you noted, those pencils are harder then the prismacolor ones, and maybe they're waxier or something, because when I used the blender pen on them it didn't do a whole lot.
