Thank you for your email. You can create this ship request from the Inbox of your account. Simply select the package and hit "Send My Packages". On the following page, you can select the option to input a new address. When selecting the shipping carrier, we suggest FedEx Ground as it is the most cost effective carrier. You may also put the RMA number in the retuturn address. If you wish to have this written on the outside of the box, you can include this as a special handling instruction by selecting this option at the time that you create a ship request.
配達業者を選ぶ時、費用効率が良いのでFedEx Groundをオススメいたします。また差出人住所に商品返品確認番号も記載されている方が良いでしょう。
もしこれを箱の外側に表示したい場合は、発送リクエストをする時にこのオプションを選び、特別扱いの指定としてこれを追加することが出来ます。
