"NEW" Horse shaving brush knots in white or brown horse hair. Softer and more flexible than boar. Even softer than some inexpensive mixed and pure badger hair knots. ANIMAL FRIENDLY- Material for horse hair shaving brushes are simply cut from the horse’s mane or tail: the animal is not harmed.
A word of caution - The only real downside to a horse hair brush is the smell. The first few times it gets wet the smell can only be described as ghastly. Do yourself a favor and wash it thoroughly with a pet shampoo, rinse well with warm water, and allow to dry before its first use. In fact, you may want to do this a couple times before you start using it. Of course, over time the smell will disappear.
