The Australian Border Force and Australian Federal Police on Monday unveiled one of their biggest seizures of illicit drugs in recent years, displaying nearly $1.25 billion AUD ($890.5 million U.S.) worth of liquid methamphetamine.

The liquid methamphetamine, also known as “ice,” was concealed in a variety of packaging, including glue bottles.

But the surreptitious smuggling packages that are garnering the most attention are these gel bra inserts.

Four Chinese nationals were arrested in the bust of bust enhancers.

“This is the largest seizure of liquid methamphetamine in Australia’s history and one of the largest drug seizures in our country’s history,” said Justice Minister Michael Keenan at the Sydney press conference, reported ITV News.

As Walter White once warned, “I am the one who knockers.”
