This is our signature product that started it all! This product is the "glue" for our Loose Sparkles. A base is required for step 1 (our Black Star Base or Metallic Shadow Sticks) for applying the sparkle eyeliner singles. Use a tapered angle liner brush to apply base then dip brush in sparkles and dab on to lock in the finest sparkles for all day wear. This base is waterproof and does not crack, dry, or absorb the sparkle.
