Due to the ongoing situation with COVID-19 shipping times can vary a lot. Shipping to North Amerika and Australia is estimated to take around a month, as carrier routes to these destinations go via ship freight

Shipping to a few countries is still suspended. I will hold any purchased items that I am unable to ship until the restrictions are lifted. Affected purchases have the option of a full refund.

You can read more about in the official German Postal Service FAQ:

International items may be subject to delays or restrictions due to the COVID-19 pandemic. These may be caused by changes in transport procedures (e.g. border controls), changes in international transport (e.g. cancellation of previously used flight connections) and/or changes in delivery procedures in the destination country (e.g. quarantine or other protective measures).”
