I use this "eraser" with Prismacolor Colored Pencils. It does fine with "lifting" color. However, it is not as kneadable as the product description would have you believe. I am going to try to keep it in a plastic baggie when not in use to see if that helps with pliability. Also, it left a sticky residue when I left it sitting on my desk. It was impossible to remove. I did not experience that with the Prismacolor kneadable brand eraser. Also, there was the question as to storing it to keep it more pliable. Of course, the Primacolor brand was much more expensive.

Great

Does not erase

This is a great value pack. I'm constantly filling my kneaded erasers with graphite.

I used charcoal on my drawing. This eraser did nothing.
