This shop is really clean and the lady working there was helpful but not overbearing. She came over to tell me about their ongoing promotions (buy 10 get 5 free for certain brands of sheet masks) then left me alone, which I prefer. I'm from the US, and prices for the Mediheal and It's Skin brand sheet masks that I bought were lower here. Of course some of the items are overpriced/more expensive than online, which is true for most asian beauty stores. Just search up prices before you buy.
I bought 6 sheet masks in total, and the lady told me to pick another one for free when I was checking out. So that was really nice. Overall, would recommend this store.
