Official merchandise from the musical HERO. Purchased at the theater during the performance. By replacing the earring charms with the key ring hardware, it becomes a keychain. I was curious about what it would look like as a keychain, so I opened it and replaced the charms with the keychain hardware, then immediately put it back. The outer bag was torn when I opened it, so I threw it away, but as I wrote above, I only checked the shape when it was a keychain, and the product itself has not been used. Thank you.
