How To Change Your Belt Buckle
It’s really easy to change the buckle on your belt; simply unsnap the poppers, take the plain buckle off the belt and thread the tip of the belt back through the new buckle. Re-fasten both of the poppers, being sure that you keep the keeper in the middle of the two poppers so that you don’t lose it.
If the buckle does up with a bar on a pin, then thread the tip of the belt, through the bar and re-fasten both of the poppers.
