A cube about ten meters long, composed of an unknown, glossy white plastic polymer. A large metal door is attached to one face of the cube. It is unclear if the door was originally with the SCP, or if someone installed it before the SCP Foundation acquired the object. The inside dimensions of this cube are roughly the same as the outside, the sides are reduced by a few centimeters, but two of the remaining three walls 1 have doors. These doors all lead to identical rooms, and each room has two more doors that lead to more identical rooms. As far as the research team was able to detect, the pattern kept repeating. The location of these doorways appears to be random; no regularity has been found to indicate which two of the three walls have doors
