where does the dust itself collect

Where does he put all those rings?

When someone collects a ring, its energy transfers into them and its physical form collapses in a burst of sparkly “dust”.

Because there is so much of this “ring dust” in the air of Mobius at all times, a person can voluntarily eject a ring from their body (to pay for something, for example) and it will instantly reform itself using that “ring dust”.

When a person is hit and loses all their rings, the rings reform slightly, but they’re unstable and will quickly disappear.
