Please be aware, that remote destinations (seen from Western Europe) may take some extended time for delivery. Also slow customs and postal service at the final destination may slow down delivery extensively. However, most parcels should arrive with 10 to 15 days after marked as “sent”.

Shipping will be as registered airmail parcel from Deutsche Post including a basic insurance (50$ per parcel). I will provide tracking codes after shipping, which allows tracking with most local postal providers like USPS etc. as long as your home country participates in the international postal tracking system. If your home country does not participate in the international postal tracking system, tracking will end most likely at the German border.

If your country participates in the international postal tracking, you will be able to track this parcel with the tools provided online by your local postal service (e.g. USPS Track & Confirm or Hongkong Post Mail Tracking)

Please be aware that there might be additional import taxes in your home country if you live outside of the EU.
