I can't seem to find out much about them online, but I know of them via adding a snail mask of theirs to my TesterKorea order I got back in May (haven't used it yet...). I got this mask in my June Beauteque Mask Maven pouch (you know, the one I got that I didn't review?? XD). Ahem. Beauteque has them in stock for $1.80..... the one I got from TK cost me 500 won, or $0.43--- the cheapest mask I own, as a matter of fact O_o.
