I'm not sure -it's a new technology brush. If your badger brush lasted a long time, then caring for this brush in a similar way will go a long way toward longevity. I'm curious myself about the bristles-they look like badger, feel similar to badger. The nice thing is there's no odor or chance of mildew because it dries quickly. Great travel brush.
