Welcome to TinyDeal,
Generally we send items with plain box package (not retail package ) in order to prevent the customs tax. The price for original box is not fixed, please send email by Customer Service Express: https://help.tinydeal.com/contact-us before that to confirm the price.
Generally the orginal box for phones are 3USD.
Before you pay for original box, you need inform us in the paypal note when you pay for product itself, note as following: please send it with original box, I paid 3USD again. And then you send 3USD to our paypal account, please also inform us in the paypal note: This is the original box fee for item XXXXX ( the order number for the item you want us send with original box)
Attention: if the item has sent out, you need to pay 5USD for sending original box only.
