Is the moonstone hazy and clean, or is it better to have more cotton wool?
It is better to have a picture of this problem, but according to your general description, your friend's will have an advantage over yours. Yours is hazy, so the cotton wool is covered. Your friend's is transparent, but it's normal to have cotton wool. If it is transparent, it is basically impossible without cotton wool. I wonder if all your friends' are blue.
