Square Enix recently updated their Japanese online store with Kingdom Hearts Silver earrings. The earrings feature either Sora’s crown or Roxas’ cross symbols; they come as an individual earring rather than a pair.
They were originally sold back in 2011, and are now being sold at 9,720 yen (approx. $87.58 USD) with pre-orders currently being accepted.
Both earrings will release on May 27, 2018.
