Description: SCP-001 is just a box that shapeshifts. When items are placed in it, the item mysteriously duplicates. A researcher was demoted to class D after cloning a particularly dangerous SCP. Nobody has tried testing it in a locked box yet. Because it can turn into the box, some say.
Addendum: There's not much known about this mysterious box.
