Set of 10 black erasers Designed to be used with Blackwing ferrule and eraser clip Blackwings have always been known for their iconic, replaceable, square erasers. To replace your eraser, slide the eraser and clip out of the ferrule, remove the clip from the old eraser, place the new eraser into the clip, and insert the new eraser and clip into the ferrule. About the Company: "Our story starts with a pencil, but it doesn’t end there. We're a team of writers, artists, musicians, designers, and DIYers who think the world is a little bit better when you slow down. We believe that thoughtful interaction with the world around us leads to a healthier life. That interaction may come from scribbling a thought in your journal, flipping through the dusty pages of a familiar book, or listening to the warm tone of your favorite record. No matter what form it takes, there's something profoundly human about it that's in our DNA."
