All of the said items have disappeared and left no traces.
The material of SCP-5092 is currently unknown, as attempts to penetrate or take a sample of SCP-5092 have been unsuccessful, however, its surface looks like it is made of some sort of metal. It is not yet known whether or not other SCPs can break through SCP-5092.
Discovery: SCP-5092 was discovered in ██████, ██████ on ██/██/20█ inside an old abandoned bank about 3 km from the town after several reports of missing people around the area. 15 cases were reported. It is most likely that the victims went inside SCP-5092 out of curiosity and were trapped inside SCP-5092. No traces of the victims were recovered in SCP-5092. SCP-5092 is now located in Site-██.
Addendum 5092-1: On ██/██/20██, a drone with a live video feed was left inside SCP-5092 to see where items inside go. After about 3 and a half minutes, the drone disappeared from SCP-5092 and was moved into an empty, big, square white area with some of the previous items tested inside SCP-5092 went. It only showed for a few seconds, before the drone lost connection with the operator. The white area to where items inside of SCP-5092 get transported is now referred to as SCP-5092-1.
Addendum 5092-2: On ██/██/20██, a foundation researcher had an incident inside the containment of SCP-5092 and had stumbled into SCP-5092. SCP-5092 closed with the researcher inside, moving the researcher to SCP-5092-1. Following this incident, SCP-5092 must remain closed at all times when not being experimented on.
