A soft, water-based formula ensures tender application. RBR use Borosilicates ( apart from the 'Anthracite Essence' shade) – minute particles of artificial quartz that fill the formula with an incredible shine and shed a coquettish lustre onto the lines. The Eyeliner allows for high coverage, dries quickly, is super long-wear and has excellent skin compatibility. An elegant brush means you can apply both fine thin lines and passionate wide lines. You can use the eyeliner alone or over your favourite eye pencils or eye shadows.
