Info about orders from USA and other countries outside the Europe:

At this time, transport capacities to the USA (and other coumtries outside of Europe) are considerably reduced. In light of this, special measures are required in order to maintain mail and parcel service. Please note that effective September 15, 2020, we will ship some products to the US via ocean freight until further notice. As a result, very lengthy transit times of at least 25 to 30 days should be expected. For destinations in the western United States or in remote regions, the transit time may be considerably longer. (6 weeks and more)
