As the locket heals damage, it optimizes the body's natural systems. However, long-term exposure produces a significant health hazard. When SCP-427 is opened and exposed to biological tissue, it rapidly regenerates cellular damage and somehow is able to purge invading compounds or infections. It displays no unusual activity when closed.
It was created after placing a pill of SCP-500 in the Input booth of SCP-914 and using the Fine setting. SCP-427 is a small, spherical, ornately carved locket made of a polished silver material. SCP-427, or the 'Lovecraftian Locket', is an SCP object that can be obtained in SCP - Containment Breach.
