Hello :)

The bristles of the product "Miobrill Greenline Vegetable Brush FSC" are specified as natural fiber. What does that mean exactly? I can't find any detailed information on this anywhere. When I google, I get many search results that also contain the word pig bristle.

Is the vegetable brush vegan or does it contain pig bristles or other animal ingredients (e.g. bone glue)?

Thank you very much and best regards,
Cristina
