This is a crystal-shaped Mickey Mouse earphone jack that I received when I purchased a Disney Mobile phone! It would light up in various colors when set in the dedicated device, but I can't confirm it now because my smartphone doesn't have an earphone jack. It's cute as a decoration too ❁⃘*.゜ Also, due to long-term home storage, I cannot guarantee its functionality, so please understand that it is non-refundable and non-returnable. The color may appear different depending on how the photo is taken. It will be sent via Yu-packet Post Mini!
