Wrapped Buckle 20mm-13h
20mm in inside diameter, 35.9mm in height, 37.7mm in width, and 3.8mm in thickness.
The pin becomes a shell round pin of the width of 3.0mm by the standard,
and 2.5mm and 3.5mm 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.
