I think it is #16 or #17. Model is packed so I can't check it's serial number.. So sorry about that. At what value do you want us to declare? Sometimes people asked for low declared value so they do not have to pay high tax, but for some countries like Hong Kong, they allow us to put at the price they purchased as no tax at all.
「具体的なサイズ」→「シリアル番号」、失礼いたしました。
