all of our sample/small quantity orders deliver by DHL company.
We got the latest news from our deliver agent. Due to the Coronavirus, now the flight is very limited, all shipments to be scheduled.
So DHL deliver time will be slower than normal delivery time. Delivery time:10-18 days
Ps. The other deliver companies （like FedEx, TNT, UPS ）also face a similar situation.
Hope you understand.
