ERASABLE WRITING COMPOSITIONS

Colored writing compositions and writing instruments produced from the compositions are provided. The compositions are erasable and can be mechanically extruded or injection molded to form writing instruments. Writing instruments produced from the compositions are resistant to breakage and may be used without supportive or rigid sheaths and may be formed into mechanical pencil cores. The compositions also display improved color vibrancy and improved laydown qualities when used to make marks on substrates.
