These sugared almonds come in colours, and as elsewhere in the Mediterranean, little baskets of them are given out to guests at weddings, baptisms, first communions, etc.
They used to throw them at the honorees, especially brides and grooms, hence the confusion with our paper confetti—only then confetti weren't almonds, which would probaby leave bruises, but candy-coated coriander (cilantro) seeds. Which is why Italians confusingly still call paper confetti coriandoli.
Sulmona (Abruzzo) and Andria (Puglia); Confetti Mario Pelino, founded in Sulmona in 1783, has a museum dedicated to them and is a member of the Henokiens Association.
