To maximise the life of your nail art brushes, ensure you follow a consistent cleaning routine after use. All remnants of polish should be removed from the brush, to help prevent damage to the bristles.
The most recommended product for removing polish is nail polish thinner, but nail polish remover is also a good option. Dip the brush in remover/thinner and wipe gently with a tissue until all product is removed, then carefully reshape the bristle with your fingers.
