The Federal Trade Commission is cracking down on Florida-based EXOTOUSA LLC d/b/a Old Southern Brass and its owner (collectively, “OSB”) for deceptive claims regarding the origin of its products and its alleged financial donations to military causes. OSB advertised that its products, including glassware, mugs, pens, and other novelty items, were made entirely in the U.S. by displaying statements on its product listings such as “100% American made,” “made right here in the United States of America,” and “100% USA made.” OSB also purported to be veteran-operated and pledged to donate 10% of its sales to military charities. The FTC’s order, finalized in January 2024, found those claims inaccurate, halted the deceptive practices, and imposed a monetary judgment against OSB.
