Item #: SCP-4137

Object Class: Safe

Special Containment Procedures: SCP-4137 is contained in a standard 'Safe' item storage locker, any personnel with level 3 security clearance or lower without supervision from personnel with level 4 security clearance or higher is not to be allowed in SCP-4137's storage locker.

Description: SCP-4137 is a hollow icosahedron standing on its point with edge lengths of 101cm. SCP-4137 is made of what appears to be steel and 100cm long fluorescent lamps with no known power source. The icosahedron is viewed to be infinitely larger in the interior than the exterior and is entirely consisted of thousands of scaffolds. Once entering SCP-4137 the area of entrance will no longer lead to the outside but instead to scaffolding, leaving the item that entered unable to leave. If the subject enters SCP-4137 backwards looking at the area of entrance then it will not disappear unless the subject obstructs the view of the exit. Once the exit is blocked, the subject can still be seen from the outside, onlookers have reported inability to enter SCP-4137 whilst there is a subject inside looking towards the onlooker.

The only known corridor type path inside SCP-4137.
