1. For the value declared on the parcel in case your wife saw it, please add this to the note when you are placing an order but we can't guarantee that we can apply this for all orders.
2. For custom invoice, please mention how much you like to declare on the invoice, once we got the order we will email the custom invoice to you.
Due to the troublesome nature of customizing a legitimate invoice, we have to charge $2 for it.
