The synthetic bristles are ultra-plush and smoother than the hair you'll find in other brushes and since they are synthetic, they are 100% cruelty-free. The soft fibres will help you create a flawless, high-definition finish in any type of light. Each brush head is hand-cut to the perfect shape, allowing for precise application from dense coverage to a soft, delicate finish. Vegan and cruelty-free.
