Japanese scientists have developed the world's thinnest condom, only 0.01 mm thick, 0.05 mm thinner than the width of a human hair. A researcher from Japan's Sagami Rubber Industry pointed out that it took more than ten years to research ultra-light polyurethane materials to make the world's thinnest condom, and conducted more than 20,000 condom pressure tests to ensure that the product is safe for people to use. The researchers are now working on thinner condoms. "As long as the market needs thinner condoms, we will continue to research condoms with a thickness of 0.008 mm and 0.009 mm." Sagami has always been a pioneer in contraceptive technology. In addition to being the first to develop colored condoms, he even manufactured a 0.02mm thick condom in 2005, which is 0.04mm thinner than the thinnest condom made in the United States.
