Changing the Parker Style Pen Refill

This pen uses Parker style refills and accepts both ballpoint and gel cartridges.  Refill by unscrewing the bottom portion of the pen.  Place the spring onto the new refill and reassemble.  The refill has two notches on the end of the refill, ensure the notches seat into the body of the pen. If the refill seems too long do not force it into the body of the pen, doing so will force the transmission into the body and the nib will not screw back onto the pen.  Instead rotate the refill  and it will drop into place and seat.
