I believe this is a rare item, but the battery box is unusable due to battery leakage. Therefore, I haven't been able to confirm if it works. It's a shame because it's almost unused, so the exterior is clean and without scratches. Please understand that this is a defective item. If anyone is able to repair it, please consider purchasing it. Thank you.
