I actually purchased this and another stain (that I know I liked ok) by a company that rhymes with "the palm" (an costs about 3 or 4 times as much as this one) for my best friend for Christmas. She is not a makeup wearer but has been interested in low maintenance, long lasting lip color so I thought some lip stains would be great for her. Well, long story short she doesn't really care for the other stain but absolutely ADORES the Tony Moly stain! I am heading to South Korea in March and while I am there I'll be going to the Tony Moly store to try and see if they have more colors for her.
Seriously though, she is completely in love with the TM lip stain. Every few days I'll either get sent a picture of her with it on or get a text about how much she loves it. She says that she can layer it and build it up till it is pretty much as opaque as a bright red lipstick and based on the pictures I have received from her I have to agree, it looks as red and opaque as some of my favorite lipsticks!
She says it isn't moisturizing (but understands that that isn't the point of a lip stain, I have tried stains from a few different brands myself and none of them have been moisturizing) but loves that she can actually put lip balm on top of the stain so her lips stay moisturized and she says it doesn't mess with the stain quality.
