SCP-735 was discovered in ███████, ████████ among the personal possessions of ████ █████ after said individual’s body had been found, having committed suicide. The SCP in question is, in appearance, a small box constructed of a brushed-aluminum-like alloy of unknown composition featuring a slot on one side. Sound is capable of being heard through this slot. When measurements are taken, the object is found to emit low-level magnetic pulses that intensify in the presence of humans. No external power source is required, and indeed the surface of the item contains no input points.
