These have all been out of production for several years. Only old stock supplies are available. This is a complete set of 13 different U. These can be used as hat pins, lapel pins, etc. All are brand new. Most have one pin on the back except the HOO YAH pin, which has 2 pins so it won’t rotate when affixed to your hat, lapel, etc. All pins are metal and include either rubber or metal clutch(s) on the back of the pin. This keeps the pin on your hat, or lapel, or wherever you put it. Each pin measures approximately 1-inch. They are very nicely detailed. Most of these were the official pins worn by Team members, and others were morale pins. SEAL TEAM ONE pin. SEAL TEAM 2 pin. SEAL TEAM THREE pin. SEAL TEAM FOUR pin. SEAL TEAM FIVE pin. SEAL TEAM SIX pin. SEAL TEAM 7 pin. SEAL TEAM 8 pin. SEAL TEAM TEN pin. HOO YAH above Trident pin. These highly collectible pins are are becoming more and more difficult to find. And good luck trying to find the complete set anywhere else.
