Per 
Idea: Anomalous object in the form of a small wooden box is discovered after all items placed inside apparently disappear. After further testing using gps trackers another similar box is discovered. Both boxes are linked and whatever is put in one box will appear in another. An incident occurs when the boxes are being tested and an explosive device contained in one of the boxes detonates killing everyone in the room.
Item #: SCP-XXXX “The Empty Box”
Object Class: Safe
Containment Procedure updated due to incident.
Special Containment Procedures:
-When examining the object it can only be opened in a blast safe room by a d-class.
Description:
SCP-XXXX-1 Small hinged box made of yew wood.
SCP-XXXX-2 Small hinged box made of ash wood.
-Celtic tree of life carved in to lid.
-Box sounds/feels empty as long as the lid is closed.
-Object placed in either box appears in which ever box is currently open.
-If both boxes are open object will appear in original box.
Addendum: [Optional additional paragraphs]
Experiment 1) testing on SCP-XXXX-1 leads to SCP-XXXX-2.
Experiment 2) incident occurs, explosion kills every one in exam room and leads to containment breach for other scp’s. Believed to be perpetrated by The Chaos Insurgency.
Experiment 3) d-class personnel put tracker in SCP-XXXX-1 to hopefully find more potential boxes and will repeat experiment in secure blast proof room.
