Christian Louboutin's iconic red sole was inspired by red nail polish and Loubi Under Red Nail Designer lets you add the signature red colour discreetly to the underside of your nails using the fine, felt-tip pen to gently apply the polish. The nail colour travels to the tip without saturating it, giving you the control and ease to create your own designs. Formulated without Toluene, Formaldehyde, or DBP. 0.2 oz. Made in USA.
