Dear SOST Customers:

We will take 7 days off because of National Day from Oct.1th to 7th. 2021. However, we still take orders during the holiday, orders will be delivered sequentially once we get back work to office. May you and your family have a nice and wonderful time.

May you be happy, safe and healthy.

Best regards.
