This is the AHC Premium Mask Pack. My brother is in the military, so I received it as a gift. Since it is a product used by many people, I tried using it without any hesitation. There are about 5 masks in one pack, and it seemed like they were being sold at a very low price. Also, what was interesting was the thermometer on the back of the mask pack; it was fascinating to learn that this indicates the optimal temperature for using the mask. After actually using the mask, my skin felt so soft and smooth. There was also plenty of ampoule, so I even applied the leftovers to my body. If you have a soldier around you, be sure to ask them for AHC Premium!
