Note: Since the arrival of the traditional Chinese Spring Festival, we will have a holiday from Jan.21 to Jan.30. During our holidays, normally you can place orders, but all parcels we will send out after Jan.27. If you have any inconvenience, you can add the goods to your shopping cart in advance, then you can buy them directly before Jan.20. So we can send your package before our vacation. And we may not be able to answer your question timely during the holidays, hope for your understanding. Thank you.
