This pressurized (nitrogen-filled) ball point was actually developed so astronauts could write in outer space but is equally wonderful for marking damp maps, writing on soggy paper placemats, or philosophizing on greasy bathroom walls. Its short, smoothly-rounded bullet shape lets you carry it in the front pocket of your jeans without getting stabbed in the thigh. Clip is removable. Specify chrome or black finish. 3.6"" closed, 5.3"" open. The ‘AG-7’ (anti-gravity) is the same model that went to the moon and features a side-button action.
