Great for tracing routes and marking mid-ride notes on the tank bag map window. The wax “leads” exit the end of the pencil with a twist of the cap and come in a variety of colors. Mark any map background or bathroom wall you may encounter in an inscription that is rain-resistant, yet wipes away with just some thumb rubbing. Ideal for writing down directions at a pay phone when you blow into town. Better than a highlighter for route-lining maps, too. Includes one pencil and four different color leads.
