Through research Lover's Lab discovered young people had concerns such as, forgetting to carry condoms, and not knowing the right timing to take the condom out. To solve these problems Lovers Lab invented the wearable condom device, “Zero One Belt”. The condom will be stored safely inside the buckle of Zero One Belt, and can be taken out with style before the act of love. By saying "Zero One" the belt will be activated and shoot out a condom to a perfect position for the wearer to catch.

"The Zero One Belt being developed to function with the Apple Watch was also part of the PR strategy.

This made the name Zero One to be remembered with the vocal recognition feature that the wearer says ""Zero One"" to the Apple Watch, the condom will fly out from the belt."

Zero One Belt was covered by numerous media, such as TV, newspaper, magazine, and online media, earning over 40 million PV, 4 billion yen worth of media exposure, and increased 44% sales than the previous year. It became the hot topics of discussion on social media among younger generation. This became the icebreaker for people to communicate openly about condoms. This project raised brand awareness, and contributed on elevating the brand image.
