Wrapped Buckle 21mm-1h
21.4mm in inside diameter, 43mm in height, 44.0mm in width, and 4.9mm in thickness.
The pin becomes a shell round pin of the width of 3.0mm by the standard,
and 2.5mm and 3.5mm and 4mm pins are also good at the business mind.
The plating of the pin always has the stock by a nickel,
gold, antique gold, a black nickel, and mortar money.
It curves and it is possible to put it though it is flat in a standard shipment.
