Wild & Stone’s natural nail brush is flexible enough to clean under your nails, firm enough to remove dirt and grime, but gentle enough not to damage the nail or scratch even the littlest of fingers. This nail brush is made from natural bristles. It is entirely plastic-free, including the packaging it will arrive in. Made from FSC® certified beechwood and natural sisal bristles, this brush is 100% biodegradable once it has come to the end of its life.
