Customs officials say they got a surprise when they found 316,000 glass bongs disguised as Christmas ornaments at the Los Angeles harbor.

U.S. Customs and Border Protection said Thursday that agents found the highly decorated drug pipes in 860 boxes shipped from China. The cargo, estimated to be worth more than $2.6 million, had been described as glass figures and Christmas ornaments.

The bongs were seized Tuesday at the Los Angeles/Long Beach port complex.

Customs spokeswoman Cristina Gamez says the importer remains under investigation and there have been no arrests.
