Pieces, short for masterpieces, are a form of graffiti that involves large, elaborate and detailed letter forms. They are one of the main forms of modern graffiti, along with tags and throw ups, and are the least controversial of the three[1] and least likely to be seen as vandalism.[citation needed]
Due to their size, pieces are almost always done in aerosol spray paint, but may use paint rollers for large fill-ins.[1]
