NYX Women's cosmetics, multicoloured, one size.

Q: Is this glitter chunky or fine?

The glitter from NYX is very fine.

Q: Can you use this for face painting

I used this in two ways. First, it has sort of a salt-shaker top so I applied glitter primer and then "shook" the glitter on until desired. I also applies it with a makeup brush for more preside designs. It wears well, lastly mostly all day. I would say yes you can use it for 'face painting'
