P-1728SF This is a handmade cufflink set of the US Army Special Forces in Sterling Silver. What better way to show you are SF than the crossed arrows with a knife. You will not find this anywhere else we hand make them ourselves. The backs of these are a solid sterling button type fastener, so they will not break and will hold up even if you have to jump out of a chopper in your Mess Dress Uniform. So if you are a Special Forces, Airborne, special operations, and special ops from WWII, Vietnam, or Desert Storm these are for you.
