I just used this face mask.  It is 3D and it fits the face fairly well.  It's a very sturdy mask unlike some that break easily.  There is enough essence on it to keep it on for the full 30 minutes without it going dry.  There is also enough essence left in the bottom of the envelope to do your neck and decollete.  I forget that this mask is supposed to do (the link won't open right now) but it felt cooling and relaxing.  I would buy it again!
