Which Is Witch? is a holographic glitter top coat. There is hex glitter in here along with tiny bar glitter. The bar glitter is actually pretty tiny, you can't really tell it's bar glitter in person due to how sparkly this is. As always, holographic goodness like this is impossible to capture....you can see the effect better in the bottle in the sun photos below. The formula was great, it was very glitter dense without being thick. I used 1 coat over Don't Burst my Bubble for the photos below.
