USPS - Chinese Zodiac - Year of the Monkey - Postage Lapel Pin - - Really neat looking lapel pins originally offered by the United States Postal Service, replicating stamps with a Chinese Lunar Series theme. They only sold them in 12 piece sets, but we were able to acquire a few sets and have made it easy for you to pick the Lunar Sign you want. The pin measures 1" by 1 1/2" and has a pin and clip-on fastener for easy attachment or removal. Makes a great stocking stuffer or Happy New Year greeting for special friends and family.
