U.S. Customs and Border Protection seized over 20,000 counterfeit Pennsylvania vehicle inspection stickers shipped from Israel to Philadelphia.

The stickers, discovered in two separate shipments on Nov. 26 and Dec. 9, were confirmed as fake by Pennsylvania authorities.

While the agency did not disclose who sent or was to receive the stickers, they would have been worth $1.4 million if real, the Associated Press has reported.

Selling counterfeit inspection stickers is illegal, with penalties including fines and jail time. No arrests have been made.
