I'm sorry your item is missing a piece.
Unfortunately, we do not have any of these items left in stock.
If you want to return the item for a refund, we can only issue a prepaid label to get it back from California, not from Japan.

Thanks for your clear explanation.
Do you have any experiences with selling drones? If you have any, can you tell us with which companies you cooperate and which products they sell.
最後の一文、「どの製品がよく売れたか」ではなく「その製品を販売したか」です。すみません。
