alert / first-aid

This is a alert against wolves for women based on modelling of buttons. when women confronted with danger, use fingers to press product in the middle of the groove, which will be opened. The sound will make 120 decibels of high-frequency alert with strong power of penetrating to warn the gunmen and attract a crowd.When women use it at night, the sound of the product could be heard in one hundred kilometers away. Press again will shut down. As a wearable product, the button is a cleverish design, which has the senses of science, technology and decorative combined blue with bright black.
