(CNN)Fifty-five pieces of rhino horn were found hidden inside shipments of plaster at Hanoi International Airport, Vietnam's state media reported Saturday.
Customs officers broke open plaster molds from 14 shipments to uncover the illegally trafficked horns, which weighed 125 kilograms (275 pounds) in total, according to the Vietnam News Agency.
Vietnam has the world's largest market for illegal rhino horn, according to the World Wildlife Fund. A single horn can fetch $100,000 in Asian countries such as China and Vietnam, where buyers believe it can cure health problems from hangovers to cancer, and use it as a lifestyle drug. The global market is thought to be worth about $500 million.
The seizure in the Vietnamese capital came after Hanoi police arrested a man accused of running a wildlife trafficking ring on July 23.
That arrest followed the discovery of seven frozen tigers in a car parked in the basement of a Hanoi skyscraper.
