SCP-714

A little chaotic building. In General, I have several other objects that came out like this, so I think that they did not come out exactly as intended. But still, this is my vision of this "ring"

"Description: Seemingly nothing more than a green jade ring, SCP-714 has been shown to be able to expand and contract to perfectly fit the finger of anyone who touches it, though this is the least important of its properties. SCP-714 only changes size when touched by a 'new' subject."
