Review on Peel Sketch Charcoal Pencils Pkg by Jennifer Roberts

These pens are great for what I need them for. For some reason these pencils are hard to find. Or I was just unlucky. They work well, but removing the paper takes a few minutes and requires more concentration than expected. The hardness/softness of these pencils is also unclear to me. I needed a medium pencil. I think the packaging says there is one hard, one soft, and one very soft, but there's no information on the pens themselves. My art teacher said I need them, so I bought them. I wonder if there is a better brand out there.
