Wanted to love and goes on easily, but honestly within 30 minutes it was already melted into the corners of my eyes and only proceeded to get worse from there. Also frustrating to have to sharpen it, when so many other brands provide twist up application.

I really enjoy the product, I just don't like that I have to sharpen it, I always feel like I lose so much of the product on getting it sharpened. Plus it would be nice if the first purchase came with it's own sharpener I don't own one specifically for makeup.
