This was the first MAC pigment I ever brought, I got it in a Tartan Tale gift set from Estee Lauders Portsmouth outlet since my getting into MAC was just after this collection was released.
MAC Teal pigment
MAC Teal pigment (dry, without a base).
I really like to wear this colour with a matte black or matte grey crease, the shimmer in this makes for a nice contrast.
Teal is permanent and can be brought from just about anywhere that sells MAC or from their website.
