This is such a great product (& fun to use!) I also use a flat liner brush, & BARELY wet it with water before dabbing into the liner. If the brush is too wet, the results won't be good (just takes a tiny bit of practice- nothing to worry about). I apply mine to the underside of my top lashes after mascara for plush-looking eyes. Stays put, doesn't smudge, & is the perfect, rich black color. I will repurchase, but this is going to last a LONG time!
