Goldwell topchic permanent hair color. 3NN Dark brown extra.

Goldwell top chic dark brown extra, permanent hair color. New, but box is damaged, hair color tube is not. Best haircolor brand I have tried to date. I'm not sure if I can write this but I have a allergy to p-phenylenediamine, my eyes would swell shut when I used hair color. this brand did not cause that reaction.
