Review (1/5): 90% nylon 10% no idea
There are a couple of natural bristles (maybe boar) the rest is nylon, you can tell because the bristles are blunt and shiny. There is a chemical smell and without even using it, some bristles have already fallen out in shipping.The quality overall is poor. Perhaps this is a fake of a good quality brush by this brand? Will attempt to return. Very disappointed.
