It's sent by using China Post Ordinary Small Packet Plus which is a cheap service of China Post. China Post doesn't provide tracking service for it after it moves for some stations. So, you can't get more update after May 17. It usually takes about 60-90 days to be delivered. If you couldn't get it in time, contact the seller to give you a solution as soon as possible.
My package was in fact not delivered. I’ve tried contacting the shipper but no response. Amazon said the seller of the item was a scammer. No trace of them anymore. I was scammed!
