Permanent Marker

Known to produce a brief yet satisfying high when sniffed, permanent markers are sometimes used for drawing on things too. The permanent nature of these markers means that the most satisfying object to deface is by far the humble whiteboard. Upon seeing your scrawls, the owner will undoubtedly assume that they were made using the correct apparatus - a whiteboard marker. Alas, when they come to remove your artwork using a whiteboard eraser, they shall be thwarted.
