Once we’ve shipped your package, we cannot do anything once it is in possession of customs officials and your country’s postal service. Please also note that if any supplementary documents are required for inspection by the local customs, the customs will contact you directly. Please pay attention to whether a letter from the customs or related documents has arrived at the designated address. If the parcel fails to pass the inspection due to your failure to actively respond to the contact of customs, you will be solely responsible.

All orders are shipped with a signature required. However, some local post service might dispatch the package directly into your mailbox without notification due to a smaller size of package.
