Faculty is one of the most well designed, beautiful concepted, and genuinely original feeling brands out there and I am so glad it exists. It is clear they have a mission and a passion and that they're doing whatever they need to in order to break down stereotypes that are well due for breaking. That said, I've been generally undewhelmed with the product itself. I've tried both the original green and the black nail polishes and while they eventually came out to beautiful colors, they took well more than one coat to get the opacity I was looking for. All of this to say, I still support it entirely (I'm wearing it right now!) and it's gorgeously designed, so you can't beat that.
I think a wider brush would be a super helpful addition. It doesn't seem like you're creating polish that's meant for delicate work and detail, so leaning into the men's beauty differentiation story and engineering a brush that can cover all my nails in one swipe would be incredible.
