Operational Status: Cassette reading: ✅ SD card reading: ✅ Touch panel: ✅ Screen protector applied immediately after purchase Button operation: ✅ Joy-Cons are almost unused Volume adjustment: ✅ Charging: ✅ TV output: ✅ This is what I could check as a layman. From the time of purchase, it was used with TV output and a separately sold wired controller. Also, the usage time was only about as long as it took to play Nobunaga's Ambition: Rebirth, and it was rarely used and mostly displayed. Therefore, I think the battery and, of course, the Joy-Cons have very little wear and tear. As for the screen, I immediately applied a protective seal at the time of purchase, so I will send it without removing it, but I don't think there are any scratches. Please understand that there are some air bubbles due to my amateur application. Also, I wiped it as much as possible for safety, but since it was mostly displayed, there may be some dust that I couldn't remove from the dock, so please understand this beforehand. The dock may have some signs of use from plugging and unplugging the wired cable, but there are no cracks or chips. I think the box and bags are probably all there, but everything in the photos is included. Shipping will be via Rakuraku Mercari delivery, with the cosmetic box wrapped in bubble wrap and placed in a separate cardboard box, and taken to a Yamato Transport sales office. This is a high-value transaction, so returns are not accepted to prevent swapping. Please consider only if you are willing to accept the item as is. Please refrain from asking for a price reduction, as I will do so at my own discretion.
