Hi Jose,

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 March 29. 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.
