Following the introduction of 0.02 mm water-based polyurethane condoms with uniform thickness in 2009, Okamoto surpassed technology with technology and launched the 0.01 series, the thinnest among all Okamoto products, which is also made of water-based polyurethane (PU). This condom has no latex smell and is suitable for those who are sensitive to latex. The Okamoto 0.01 is made in Japan at the Okamoto Co., Ltd. Ibaraki factory in Ryuzaki City, Ibaraki Prefecture, and the product quality is reliable and trustworthy. Compared with Okamoto 0.02, Okamoto 0.01 showed nearly 2 times the extension force in the experiment of adding 350ml of water, the softness is amazing, it will not feel tight when wearing, and the tightness meets the requirement of “not falling off” in use. . In terms of safety, Okamoto achieved “no damage” and “no leakage” through rupture experiments, water leakage experiments, and pinhole inspections.
