Question about Body Vital Hand massage brush with wooden knob

The manufacturer is not diaqua, it is a dealer!
The manufacturer is: Crol&Denecke!

Horsehair and natural fibre, natural wood! Unfortunately I can't find anything about the pimples or the plastic holding plate! (Between wood and bristles).
The plastic is a high quality plastic as I see it and the nubs are made of high quality rubber!

It doesn't stink! That's a good sign!
If you bend the nubs a bit to provoke the smell, it's pleasantly reminiscent of marzipan!^^ lel
So you don't have to have any thanks!
High quality, a very good massage brush!

Unfortunately, the manufacturer does not provide any information on this, I'm sorry.
