Pressurized "Bic" Pen Ink Cartridge And Spring Tip
Posted: Sun Oct 15, 2006 6:27 am
A ball point pen that is spring loaded also at the ink ball, a very small degree of pressure is applied on the ink ball. The pressure in the ink tube lets out a steady, but controlled amount of ink, consistenetly with only one pressure level coming out, with the ink restriction of the opening of the spring loaded pen at the ink ball.
No matter how light or hard you push down, you always get the same amount of ink from the ink ball tip, making writing lightly with very little pressure and letting out the maximum controlled amount out at any time, to ease your fingers and hands from injury, pain, or fatigue over continous usage.
