Police in Vietnam have taken away thousands of counterfeit condoms and lubricants following a sudden raid on a facility.

The products are knock-offs of famous brands and were falsely labeled as being manufactured in Malaysia and Russia, officers in Dong Nai Province said on Tuesday.

Police eventually confiscated 1,919 boxes of condoms and 330 tubes of Croc massage gel with ‘made-in-Malaysia’ tags, and 137 tubes of ‘made-in-Russia’ Titan lube.

Officers also discovered and held 340kg of raw materials to make condoms, 53.5kg of packaging paper, 29kg of lube oil and 35kg of ‘erection oil,’ besides several pieces of equipment and machinery.

The facility, located in the provincial capital of Bien Hoa, is run by Nguyen Thi Xuan Vinh, 29, who failed to show officers her business license and any receipt for the raw materials.

Vinh confessed to police that she had imported all materials from dubious sources in China.

She would mostly distribute the counterfeits to Ho Chi Minh City and customers who placed orders online.

Last year, Hanoi police seized one metric tons of counterfeit condoms, which were made from Chinese materials but sold as ‘made in Malaysia’ products.

The crackdown came only six months after police in the Vietnamese capital busted a similar facility and confiscated 700,000 fake condoms.

According to experts, counterfeit condoms will likely not protect against pregnancy and sexually transmitted diseases, not to mention that the low-quality materials they are made from can also cause health problems.

The fake products could cause allergy or even infertility to users, doctors warn.
