Marble’s brass body pin-on compasses are a 100 year old tradition with hunters, campers, hikers and explorers worldwide.  Each component of the compass is CNC precision machined from solid hi-grade brass bar stock.  The brass casing is strong, malleable and won’t rust.  The pin version uses a large brass safety pin to fasten securely to your jacket or shirt.  The revolving black and silver face has a luminous dot at the North position.
