SONY Genuine Remote Control RMF-TX 431J! I was using 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'd like to pass it on to someone who will also take good care of it! For a limited time, I'm offering a "5%" discount to those who follow me! Feel free to contact me! It's not too late to start now! ↓ You can see my other items here #Perona'sRoom If you have any questions, such as price negotiations, requests for additional photos, or if you want to know more about the product, please feel free to ask^^ To prevent "return swap fraud," which has been in the news regarding Mercari recently, I'm asking for no returns, no exchanges, and no cancellations (3N). Thank you for your understanding. Please feel free to ask any questions you may have before purchasing! Thank you!
