Review (4/5): Nice Masks, but Watch Pricing!
I purchased a multi-pack (direct from South Korea) that contains all of the types. They are different in that the essence is not at all watery, but rather a very thick gel. The masks can easily been worn for close to an hour before all the jelly is absorbed out of it. The overall fit is good, and there are enough cuts to fit a variety of face shapes.
The results are nice, and each mask does deliver what it sets out to do. The reason for four stars instead of five is because the remaining gel stayed very tacky (at least on me), even a few hours after removing it. So much so that I wound up wiping the remainder off with a damp cloth before finishing up with my other products. Products do tend to hover over my skin, rather than completely absorbing. So this observation may not apply if you are lucky enough to have the type of skin that absorbs products easily.
Are they worth trying? Yes, absolutely. Are they worth $10 each (the price on the page I'm reviewing is 10 for $99.99)? NO WAY. You can find a 10 pc pack for under $20 (including shipping), and I got a 5 pc pack for $12 and change.
