Yesterday, I received an update from Faber-Castell. They sent me two statements to publish here: the English Version and a German Version for you to read. According to those, the vast majority of products is free of animal derivatives.
They are still a cruelty-free company on all levels. They do not test on animals nor commission it by other parties.
I did reach out to them again today, to double check once more that all of the products previously listed in my February 2022 update are still free of animal derivatives and I also asked about the Fude Pens, which I forgot to ask about in December.
