Chalk Pencils have a smooth, blendable formula for use in traditional fine arts, scrapbooks or memory books. They're perfect for lettering, outlining, stripes, borders, shading, accents, embellishments, roughing and aging effects. Chalk Pencils can be blended easily with a finger, paper stump, kneaded eraser, or tissue. For a dramatic effect, use them on a dark colored paper with a rough surface. Each acid-free pencil is encased in cedar wood and tipped with General's extra soft vinyl eraser. Pencils are pre-sharpened .
