"What to say? I LOVE THEM! *-* they look artificial, but they are amazing *////* I love the fact of the black ring on the edge of the circle, also how the grey degraded into light brown, and also that the circle in the center (the transparent to see xD ) isn't a perfect circle, it is like a degraded (see detail pictures below). In brown eyes that effect looks amazing, and I love it ^^ that's my most sincere opinion."
