CHICAGO (AP) — Federal officers have seized 450 fake iPhone cases during an inspection at a facility at Chicago’s O’Hare International Airport. U.S. Customs and Border Protection says the counterfeit cases were in a package that originated from Hong Kong and was headed to an Amazon facility in Joliet.

The cases are described as being of poor quality and design. Authorities say that number of actual iPhone cases at the manufacturer’s suggested retail price would be valued at $17,550.

Nearly 200 counterfeit watches were found in late June and early July at a mail facility at the airport. Officers inspected 175 parcels containing 193 watches due to incorrect manifests or X-ray anomalies.
