Special Containment Procedures: SCP-XXXX-1 is to be secured to the floor in the corner of a standard humanoid containment chamber facing the opposite corner. Any entrances to SCP-XXXX-1's containment chamber must be located behind SCP-XXXX-1 to make it unavailable to SCP-XXXX-2. All items provided to SCP-XXXX-2 are to be reflected and removed from SCP-XXXX-1's containment chamber to prevent unnecessary waste of foundation resources. An exception to this rule is a retrieval bin that is to be used to retrieve any items from SCP-XXXX-2 safely.
SCP-XXXX-3 is to be kept in a large low priority anomalies storage locker.
Description: SCP-XXXX-1 is a glassless free-standing mirror measuring 182.88cm by 91.44cm. SCP-XXXX-1 is the apparent entryway to an extradimensional space, hereby referred to as SCP-XXXX-1's reflection. When undisturbed, SCP-XXXX-1's reflection perfectly mirrors our reality and would be indistinguishable from a regular mirror's reflection if it wasn't for SCP-XXXX-2 presence. It is unknown if SCP-XXXX-1 anomalies effect is inherent to the item or if SCP-XXXX-2 or some other unknown source created it.
SCP-XXXX-2 is a 159cm woman who is currently residing in SCP-XXXX-1's reflection. SCP-XXXX-2 has not shown a need to consume food to survive.1 SCP-XXXX-2 apparently entered SCP-XXXX-1's reflection when they tripped, falling onto SCP-XXXX-1 and entering SCP-XXXX-1's reflection, instead of any other logical result. SCP-XXXX-2 reports that this is when SCP-XXXX-3 fell out of SCP-XXXX-1. SCP-XXXX-2 has been unable to leave SCP-XXXX-1's reflection, and this anomaly has failed to be reproduced.
SCP-XXXX-2 has shown some ability to manipulate objects outside of SCP-XXXX-1's reflection by interacting with the object's equivalent in SCP-XXXX-1's reflection. With SCP-XXXX-2, cooperation objects can be removed from SCP-XXXX-1 containment chamber while staying in SCP-XXXX-1's reflection. For more information on SCP-XXXX-2 and their interactions with SCP-XXXX-1's reflection, see test logs.
SCP-XXXX-3 is a non-living biological object with an appearance identical to SCP-XXXX-2. Notably, SCP-XXXX-3 autopsy revealed it to be affected by situs inversus2 and genetic testing has returned negative.
