This pen features the "infinity" band - a revolutionary 3-D band style exclusive to the Apollo Infinity™. The pen keeps the same elegant rounded profile of the original Apollo Elite™. Includes smooth writing Black Gel ink. The Gold Titanium (TN) plating looks just like gold and is absolutely permanent. It will even outlast our guaranteed standard gold finishes. All TN kits are stamped with a "TN" indicia on the pen clip to authenticate it’s Titanium status.
