Promotional magnets are gifts included with a product, placed inside its packaging. They are often used to boost sales of everyday consumer goods or food, especially when offered as collectibles, such as trading cards or football player sets. In addition to their collectability, promotional magnets have the advantage of being designed to be displayed on a refrigerator, thus offering strategic visibility. Some promotional magnet collections become so popular that they generate intense online trading and reselling activity. It’s important to note that promotional magnets differ from advertising magnets in their use. A concrete example would be a brand that has set up its own online platform or community for magnet trading.
