My order is with Customs, should I be concerned?

The Customs process is nothing to be concerned about. 

Any order shipped internationally needs to pass through Customs as part of its journey. Your order being with Customs just means that it is being processed by the postal system in its destination country.

We have no control over the speed of Customs once it reaches the destination country.

Customs clearance can take less than 24 hours, but may take several days depending on the destination countries protocol at the time.
