Chain Maille Knot Fiddle Cufflinks - Sterling Silver

I designed something similar to this for a friend, knowing he'd be nervous at his wedding - it's something subtle to fiddle with when you need to look your best. The rings are mostly free moving and rotate around each other.

They have a U arm fitting which can easily be knocked into place. 

The knot is 1.2cm (approx 1/2") to be visible but not too "out there" for a formal occasion.
