Recommendations for very affordable face masks

This is a cheap face mask I use. It costs a mere 180 won, which is a really low price haha. I’ve tried every expensive mask imaginable. However, since masks need to be used for no more than 20 minutes, I read that expensive ones aren't very effective and that it's better to use cheap ones frequently. After that, I decided to prioritize quantity over price. Then, a friend recommended the Food Aholic mask, and I started using it. It worked much better than I expected. I've only tried the cucumber flavor so far, but I plan to slowly try the others. I highly recommend this mask to anyone looking for a generous amount haha.
