I believe this product is used for watching videos, such as Blu-rays. It's a rare and valuable item, but I apologize that I don't have more detailed information as it was never sold in Japan. It's a used item, and the functionality has been confirmed at a reuse shop, and it hasn't been opened since then. The product itself is in good condition, but the box has some damage, please check the images.
