Hi Stream,

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 in China. So, you can't get more update after Dec. 3. It usually takes about 40-60 days to be delivered. If you couldn't get it before the delivery deadline, contact the seller to give you a solution or open a dispute on AliExpress to get refund as soon as possible.
