Nostalgia, as an emotion that describes a preference for the past and past-related objects, provides benefits in periods of high uncertainty by acting as a mediator in creating a sense of security and perception of social connectedness and has the characteristics of a positive and often motivating effect in nostalgic people. In the last few years, there has been an emphasis on the trend of consumer nostalgia that is visible in the media, and at the same time with the recent need for adaptation in the context of life changes. The positive effects of nostalgia have been noted by marketers who often use appeals to different emotions in their marketing strategies to stimulate the desired behavioral responses of consumers. Elements that act as references to some individual but more collective past experience of the consumer are now widely used in various marketing activities such as in product design and product packaging, in traditional and digital marketing communication and for positioning the brand in the minds of consumers as nostalgic. The stated use of nostalgia in marketing aims to primarily stimulate nostalgia in consumers and the positive associations and attitudes based on them towards the brand, which are considered to have an influence on consumer decisions. On the basis of previous findings regarding the effects of nostalgia and how it is used in marketing strategies, research was conducted on the role of nostalgia in brand management, i.e., in selected marketing activities of communication and product design on the choice within the selected product brand and on the consumer's purchase intention in the Republic of Croatia. The selected marketing activities relate to the nostalgic packaging design and social media posts of the Čokolino food product brand. The results of the research primarily confirmed the possibility of the mentioned marketing activities in evoking nostalgia in consumers and showed that in a choice situation, consumers will be more inclined to choose a product with a nostalgic packaging design compared to non-nostalgic ones, and that the purchase intention is also favorable for nostalgic marketing activities. The aforementioned empirical findings act as a complement to the existing marketing literature, especially in the context of marketing nostalgia.
