Noshi

Noshi (熨斗) is a small folded paper ornament attached to the corner of a formal, celebratory Japanese gift. It traces back to a custom of attaching a thin, stretched strip of dried abalone to gifts as a wish for longevity, since abalone was a valued, durable marine product; the paper ornament used today is a stylized descendant of that original offering. It’s reserved for formal occasions like weddings and births, not everyday gift-giving such as standard omiyage, which is typically wrapped without it.
