SONY's genuine remote control, the RMF-TX 431J! I used it with my BRAVIA series TV! I haven't checked every single button, but I never had any problems using it regularly. I've taken good care of this item, so I hope to pass it on to someone who will appreciate it! For a limited time, I'm offering a "5%" discount to followers! Feel free to contact me! It's not too late to follow now. ↓ You can see my other items here: #Perona'sRoom Please feel free to ask about price negotiations, requests for additional photos, or anything else you'd like to know about the product! To prevent "return swap fraud," which has been in the news regarding Mercari, I'm asking for no returns, no exchanges, and no refunds (3N). Thank you for your understanding. Please feel free to ask any questions you may have before purchasing! Thank you!
