As the only manufacturer of metal whistles in the United States, American Whistle Corporation can custom imprint our solid brass whistles with your logo for promotional handouts or safety programs. We also provide custom imprinted lanyards to attach to your whistle, keys or badge. Don't forget to ask us about our American Classic Gold Award Whistle. This 24K gold-plated whistle in a walnut display case is the same one the NFL purchases for the Super Bowl referees. Give this unique gift for a special promotion, retirement or thank you.
