A major part of high school is showing loyalty to your high school, and that usually involves the school band. Along with the school cheerleaders, almost no other school group is as attached to school spirit as the band is; no other group does as much fund-raising for various school projects as the band does. One of the products that the band uses is band spirit magnets; these small refrigerator magnets have the school insignia, motto, and mascot on them and can be displayed almost anywhere. They are small. cheap, and show everyone which school you belong to beyond question.
They may be small, but they can show exactly where your loyalties belong, sometimes in the most fun way possible. The magnets can help build a link between two people, whether fellow students or rivals, making them well worth it even for non-students.
