If you are not home and the item cannot fit in your mailbox, a notification from Japan Post will be left, and the item will be held at your local post office for one week. Please check the notification and request redelivery from Japan Post. If you cannot find the notification, please contact your local post office before the storage period expires. We are sorry, but we do not negotiate prices. Please do not ask for any price reductions on the items we sell. We will block any comments that request unreasonable price reductions. If multiple items can be shipped together, we will ship them together as much as possible, but we will not offer any discounts in such cases. Please be aware of this beforehand. Also, we do not accept requests for additional images.
