Distinguishing between the right and the reverse side of condoms is always hard. Every time we squint our eyes but still fail to wear them properly. Once the reverse side is used, the danger rises. However, using a new one is also wasteful. The key feature of our design is the raised dot at its top, which allows us to recognize the right side immediately.
