In Italy when you go to a wedding or baptism ceremony you will receive a gift from newlyweds or during baptism from parents of the child.
Usually it is something made from silver, for instance I received a silver spoon and a silver tea pot. It can be also a crystal vase or a typical, hand-made Sicilian vase.
Plus you will receive confetti: sweet almonds wrap in a small, cute bag.
I was very surprised at first when we receive "la bomboniera" at the wedding of my husband's brother, but later on I discovered that Italians like a lot to give small souvenirs during different occasions just to remember them.
All around Italy there are thousand of shops which sell only le bomboniere.
