Merry Christmas 2021!

Dear customers and business partners,

a year ago we had hoped to put the crisis behind us shortly.

But, again, we were presented with the same and also completely new challenges in 2021.

However, as before, we were able to count on you and your loyalty. Although this was a difficult year for everyone, it was a pleasure working with and for each of you. Thank you for your continued support of our business!

We wish you and your loved ones a wonderful Christmas as well as success, good health and good luck for 2022. We hope the new year will be a little less exciting and see the return of some long-awaited normalcy.

Best wishes,
Roselies Gersdorf and the Haase team
