Hi richard knight,

They are sent by using China Post Ordinary Packet Plus which is a cheap service of China Post. China Post doesn't provide tracking service for them after they arrive at the US secondary processing center. So, you can't get more update for them. It usually takes about 60-90 days to be delivered. If you couldn't get them in time, you need to contact the seller to give you a solution as soon as possible.
