Hi BUT,
It's sent by using China Post Ordinary Packet Plus which is a cheap service of China Post. China Post doesn't provide tracking service for it after it arrives in France. So, you can't get more update after July 4. It usually takes about 60-90 days to be delivered. If you couldn't get it in time, you need to contact the seller to give you a solution.
