I absolutely feel like the majority of indie makers (of perfume, bath and body, cosmetics, and polish) are in it for the love of the craft and wouldn't be likely to risk endangering customers. I tend to avoid the very obscure and I always look for reviews, particularly from people that I am familiar with. I will continue to purchase indie polish, but I will probably be a little wary before purchasing from someone new.
I've never bought anything from Mentality, but I have considered it. I really hope that he has to face the music.
