 SCP-436 is a small locket, apparently made from gold. When opened, an inlaid photograph can be seen. It is unknown if the photograph is the source of SCP-436's effect, because this cannot be tested. Individuals affected by SCP-436 will have their height and weight altered, and in some cases, their personality, ability to learn, perform calculations, and make judgments will be impaired. Medical conditions, such as data expunged, and in particular cancer, have occurred.
