Wrapped Buckle 20mm-31h
20.8mm in inside diameter, 42mm in height, 31mm in width, and 7mm in thickness.
The pin becomes a shell round pin of the width of 3.0mm by the standard,
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.
