THE METRO BUCKLE SET A DEPLOYMENT TYPE BUCKLE WITH NO MOVING PARTS. IT IS A VERY WEARABLE BUCKLE FOR MOST OCCASIONS. THE BUCKLE ALONE CAN BE WORN FOR MORE FORMAL EVENTS AND THE KEEPER ADDED FOR MORE CASUAL OCCASIONS. IT IS AVAILABLE IN A RANGE OF CHOICES. THE METRO BUCKLE SET IS THE ONE I WEAR MOST OF THE TIME.
