The colors are well-pigmented, with even the lightest colors creating very vibrant tones. The bright colors and smooth texture remind me a lot of the Prismacolor colored pencils that were the Cadillac of my high school art classes. Overall a good coloring experience, though not as nice as the Derwent colored pencils that I've been using over the past decade.
One thing these colored pencils have that most don't is the signature flat Blackwing eraser. Erasers aren't usually as effective on colored pencils as they are on graphite, and that's still the case here. The eraser formula on these is different than for a graphite pencil. They're paler, more textured, and a little crumbly, because Blackwing has included sand in them to make them more effective. They work better than a regular pencil eraser would, but you can see that they still aren't removing much of the pigment from the page. A bit, yes, but the erased lines are still visible except in the very palest colors. The erasers are refillable, though, so if you find yourself erasing a lot, you can replace the end.
