I used this with my natural hair/face rather than a cosplay.
They were extremely easy to put in and there was no stinging.
The black was very dark and made my eyes look a lot bigger.
Unfortunately because my eyes are very pale, you could see them around the centre as the contact colour didn't stretch that far so I had a green ring around the pupil.
I do love them though and they're great for everyday wear.
Probably best suited to those with darker eyes to begin with.
