Are you tired of using colored pencils to plot your campaign moves? Do your battle report pics lack punch?
The arrows are made of brightly colored hard plastic. Not bendable by hand (I didn't try the hair dryer trick on them). The curve makes them easier to pick up. Should be easily repainted if you prefer more serious colors.
The magnets are in the arrow heads, and are small but powerful. Polarities vary. Could be used on magnetic whiteboards to display whose turn it is or what phase you're on.
