PROBLEM
People sometimes lose valuable belongings such as cell phone or wallet in a public restroom. We suggest a new toilet door lock system that can reduce the incidents of lost.
Have you ever lost your cellphone or wallet in a public restroom?
If you use Toilock, that kind of bad situation won’t be happen again.
