here is the Chameleon update:
all Chameleon products are free of animal derivatives except the Chameleon pencils, those contain a small portion of beeswax.
They state, they are a PETA approved cruelty -free company and they do not test on animals. Here is the link they provided.

I just sent out enquiries to Chameleon Pens for an information update (2017 entry ) as well as enquiries to Tim Holtz (about Distress Ink pads) and Tsukineko (ink pads; Memento, Brilliance, Versafine).
If you know about other ink pad brands, you want me to look into, please don’t hesitate to let me know.
