SONY WF-1000XM5 Charging Case Only Functionality confirmed. Due to being a used item, there are some scratches on the charging case. Please consider purchasing only if you understand that this is a used item. Please refrain from purchasing if you are a nervous buyer, as this is a used item. For electronic appliances, I have checked the operation of items that can be tested before listing (items with unconfirmed operation are noted), but I do not guarantee their operation, so please understand and acknowledge this before considering a purchase. Also, to prevent swapping, we cannot accept returns or refunds after purchase, so please also be aware of this. Please be sure to check and understand the above conditions before purchasing.
