At Nail Matrix we use disposable liners for all of our pedicures. The reason we use disposable liners is because we want to reduce any risk of you getting a toenail fungus or skin infection.
Also at Nail Matrix we use OPI, Essie, China Glaze and Orly Nail Polish. Nail polish has a shelf life and once the polish begins to thicken we toss it, or give to a cute little girl to play dress up. We do not thin it out with acetone or a nail polish thinner, as both items destroy the polish and your natural nail.
