What do stamps (邮票) smell like? In France, the national post office, La Poste, made a special stamp. It smells like a warm and sweet croissant (牛角包)! The croissant is a world-famous food from France, and the post office made about 600,000 stamps to celebrate it. People love stamps very much. The stamps can be used to send letters, too, so people can share the yummy smell all around the world!
