Ticklemethu- It something for the tips of your eyelash. Like it comes in a little click pen then and I'm guessing you squeeze a little on the tip of your eyelash and when it dries it should look shine like a little crystal or it drys like a crystal (????). I have no idea, that's what I figured when I saw it at the store. I've seen this same product by another company which just isn't coming to mind yet.
I got that $5.00 off your purchase with my Duane Reade card so I think I'm going to try it. Just wanted to know if anyone else did yet. Although the colors from collection do look good.
