This device looks like it is grafted from carefully wrought metal components, that fit together almost seamlessly in the shape of a half-sphere with four diamond-shaped sparings in its surface. The device is three and a half inches in diameter, and the top of the device contains a button with multiple usages. Sharing the streamlined appearance of all Aperture Magic apparel, a voice box is a device that can record and play back sounds, making it very useful for espionage missions, interrogations and other such purposes. When a voice box is purchased, it comes in its own black safety box together with a small, leather bound booklet detailing its operations. The manual contains the following information, drawn in carefully calligraphed common.
