Hey CH,
As soon as you receive a tracking number, it means the order HAS in fact shipped and left our warehouse. USPS, especially during the holidays, can take a while to update their systems. This is why it probably still says "electronic shipping information received" (and nothing further).
I checked into your order specifically, and it was shipped out on December 8th. Note that with the shipping method you selected (First Class International), it can take 7-21 business days to arrive. This excludes weekends. All in all, please remain patient, and they will arrive soon!
If you have any further questions or concerns, always feel free to submit a
support ticket, as these types of issues are much more quickly and easily handled in that department than on the forums.
Thanks guys, and have an awesome Holiday!
