Does Taobao need packaging for trade-in

Yes Trade-in of Taobao means that you buy a commodity on Taobao, value similar old products in your hand, and then mail them to recyclers. The other party will give you a certain amount of red envelopes, and after submitting the order, you will receive a message of trade-in. Moreover, when mailing old products, users don't need to pay the freight, just pack the old products according to the SMS prompt.
