Okamoto Zero One is an ultra-thin condom that uses Okamoto Co., Ltd.’s proprietary technology to achieve auniform thickness in the 0.01 mm range from base to tip. Using ISO-specified measurement methods, it achieves the 0.01 mm range at all three points: top, center, and bottom. It is made withwater-based polyurethane, making it safe for people with latex allergies to use. The high thermal conductivity unique to polyurethane delivers a “bare-skin sensation” in which body heat is transmitted directly. It also has no rubber odor at all, providing a clean feel during use. The individual package is marked “male side,” making it easy to identify the front and back even in the dark. This high-quality, completely Japanese-made condom is manufactured at Okamoto’s Ibaraki factory.
- Be careful to keep it away from fingernails, teeth, and sharp objects.
- Put it on after achieving an erection and always before starting sexual activity.
- Check the “male side” on the individual package before putting it on.
- Gently press the air reservoir at the tip to expel the air before putting it on.
- After use, do not flush it down the toilet; dispose of it in a trash bin.
- Use each one only once.
- Because it is less elastic than latex, a poor fit may cause a loose, crinkly sensation.
