This is a must for every woman's beauty bag. I use this with the Alan eyeliner flat brush and it has amazing staying power yet washes clean with normal face soap and water. The product lasts a long time too I think I have had my liner cake for almost 2 years now and use it almost daily.
I love adding glitter to my eye makeup routine for fun nights out. This can be played up and be intense of down played for a more "I see a sparkle when you smile look" I like to use this over/ on top of a liquid liner like Stila or Kat Von D
