Make-up brushes present a challenge; most are made from from animal hair like sable, badger, squirrel, pony, or goat.

Instead of participating in the skinning of our animal friends, try EcoTools.  Endorsed by vegan Alicia Silverstone, these brushes are soft, durable, non-shedding, and cruelty-free.  They have a high-end feel at a drugstore price.
