Bracelet has a rowing blade attached via loops that allow the wearer to open it, slide wrist in sideways, and reclasp into ring.  The metal will develop greater springing action over time but occasionally will require opening the wire portion wider so it remains taught against the ring on the blade and stays closed.

The tulip blade, measures 6mm wide by 15mm long. Body of bracelet is round wire.

The bracelet measures ~8 outside circumference, fits wrist up to 7.25 inch circumference.
