This exquisite, one of kind, handcrafted pen is made from Gary Oak. It features the Insignia worn by U.S. Military personnel who have qualified in Submarines. To earn the right to wear "fish", prospective submariners complete an extensive qualification process that lasts about one year (for both enlisted and officers, though the two programs differ significantly) and covers virtually all of the submarine's systems. Once an enlisted sailor has earned the right to wear the "dolphins", (SS) is added after his rate of rank that stands for "Submarine Specialist".
