6-7 years of using these two products and I don’t see me changing them any time soon! Nars concealer is chestnut. Sometimes I use the color caramel for extra brightness. But I normally stay with chestnut because I don’t like a very bright under eye. This brush comes in a set, but all the brushes are phenomenal and at an unbeatable price.
