Dear Customer: Due to the impact of the new Coronary Pneumonia virus, our store has made the following adjustments to logistics transportation: 1. In order to ensure the successful delivery of packages, we will change all standard logistics transportation methods to AliExpress Standard Shipping. It is a logistics transportation method recognized by the platform with shorter arrival time and more assurance. 2. If you choose economic logistics, when your order amount is more than US $ 12, we will upgrade it to AliExpress Standard Shipping for free. It is recommended that you choose AliExpress Standard Shipping when you purchase. If you have any questions, please feel free to contact customer service, thank you for your support and trust, wish you a good day!
