Dear Customers,

As a result of urgent rebuilding measures, we will be able to continue our business operations only to a very limited extent from November 29, 2017 until probably January 2018.

We strive to handle very urgent orders, but can not guarantee that.

We will inform you as soon as normal business operations are possible without restriction.

We ask for your understanding and apologize for the inconvenience.
