The Romel Rein Connectors come in two options Sterling overlay and Silver Plated. This option is for the Silver plated pair. Both are hand engaved and look stunning. The Silver Plated set has an electorplated lay of sterling silver over a base metal for strength. These can be added to any set of reins and can be used either direction based upon the size of the ring of the bit. Be sure to check your screw tightness consistently for safety.
