This hard-shelled protective case is designed to safely store and transport your equipment such as cameras, electronic devices, or test and measurement meters. The pre-cut foam squares allow for customizing the interior while the pressure equalization valve creates an airtight and watertight seal protecting your devices. 

The manual relief valve prevents altitude and temperature changes from causing differences in air pressure between the inside and outside of the box, which can effectively prevent the box from being out of shape, bursting, getting wet and unable to open.
