Medical Twist Pen in Antique Brass Finish with DiamondCast Copperline Resin Body

A Medical theme twist pen in Antique Brass finish, with a DiamondCast Copperline Resin body. The pen uses a standard Parker type ball point pen cartridge (black ink included). The pen as shown is just over 5.4" in length, and just under 0.6" diameter at the widest point.

To use the pen, the ink ball-point can be extended and retracted by holding the "Heart Beat" part above the pen tip, and twisting the upper section of the pen. To change the ink cartridge, hold the "Heart Beat" section, unscrew the tip of the pen, and remove the old cartridge. Transfer the spring from the old cartridge to the new cartridge, small end first, and insert the replacement cartridge into the pen body. Then simply screw the pen tip back onto the pen body.
