 SCP-216 is a 35.6 cm or 14-inch high iron safe with a multiple-dial combination lock. The lock has seven dials each, with numbers ranging from 0 to 9. The combination cannot be changed while the door is open. The weight of the device appears to fluctuate in an obtuse manner. The door of SCP-216 can always be opened, but the accessible interior space appears to change depending on the currently entered combination. It is speculated that every possible lock combination results in a different interior, and that there are approximately four million available compartments. It is unknown how many objects currently reside inside SCP-216.
