This is a perfect everyday use whethers it's being used at home, an executive desk, a meeting or in the field... it's an all around great ballpoint pen.  It is the perfect "in between" size; smaller than the classic American-style pens, but larger and easier to grip than the slim-style pens.  
 
Double twist mechanism turns left or right to extend the ball point, turn to center to retract.
 
This pen accepts Parker style ink / gel ink refills once origonal is empty.
