Hello friend, because of the current global epidemic situation, the transportation of goods will be relatively slow. We cannot guarantee that the transportation time can be as fast as before. If you cannot wait for a long delivery time, please do not click to order. If the buyer applies for a refund on the ground that the goods are in transit, we will refuse.thank you!
（If you want to receive the goods relatively quickly, you can choose to use DHL, which will be faster than China Post's small package, but its cost is relatively high.）
