ONKYO Oshi no Ko Collaboration Earphones Ai Hoshino Version Wireless Earphones CP-TWS01A "Oshi no Ko" Collaboration Model Brand new, unused item. I have confirmed that it can be opened and charged for the purpose of listing it. This is a made-to-order product that is no longer sold. I have stored it at home after purchase, so please understand that it has been in someone's possession once, and there may be oversights in the details. As unused items are not often available, I would be happy if someone looking for this item could use it. Thank you very much!
