Researcher Wang Tingting gives a demonstration using coloured dyes that claims to show how Safedom's condoms prevent the transmission of the Hepatitis B virus at a factory in Zhaoyuan, 100 km (62 miles) south of Yantai, in Shandong Province February 6, 2012. Safedom turned its back on the low-margin, guaranteed-business sales to the Chinese government?s family planning program 11 months ago, and decided to shift to where the money is: the higher end of the general public market. Claiming to be the fourth-largest condom maker in China by revenue, after three foreign brands, they are hoping to sell one billion condoms this year with the launch of its ?Take Me? condom, aimed at women consumers.
