I forgot I had already purchased this from the official store and bought it again. This lip mask removes excess dead skin cells and sebum, leaving your lips smooth. It's a peel-off type; apply it and peel it off after about 10 minutes. After use, your lips will be incredibly smooth and you'll want to touch them constantly. The plumping menthol provides a cooling effect, refreshing and cooling down the heat in your lips. I will ship via Yu-packet Post Mini. I just received it, but please understand that it has been stored by a private individual. Thank you.
