I like these sheet masks, but they aren't as great as some other Etude House masks. These particular masks use a lotion-type of essence as opposed to the more traditional serum-y essences used in other sheet masks. I happen to like the lotion type of mask, but some are turned off by it. The mask itself is rather thick cotton, which actually leads to a very nice application and easy wear. I bought these hoping they would be ultra-moisturizing, but I find they are less moisturizing than many of my other lotion-type sheet masks, including the Etude House Royal Jelly mask. They are OK and I will continue to use them, but I will not go out of my way to repurchase the Snail mask.
