The thing we’ve noticed about colored pencils is, they don’t last forever. The more we draw with them, the shorter they get. So, we just keep replacing them. If you’re in the, same boat, here are (2) packs of great ones, non-toxic, 7” long, round, pre-sharpened and in a plastic case, from Leisure Arts®. You pick: the (24)-pack with browns, reds, yellows, greens, blues, purples, pinks and classic white, gray and black; or the (80)-pack with all those colors and more. So, we guess they could be for black and white if you really wanted.
