I got this polish recently from Apothica.com. I don't wear dark colors really often because of the staining, but I love them. I'm drawn to them. This is definitely one of those polishes that caught my eye. Then I read the description, a black shade with a red-orange shimmer, and had to have it.
I love the golden glow in the bottle. I'm imagine this would really come to life in the sun, but I only wore it long enough to swatch it, so I can't say. Thought I didn't have it on long, it did stain a bit when I took it off. Sometimes when I plan to wear a dark color or a really pigmented blue or really just anything known to stain, I will double up on my base coat. I love how the golden glow warms up the black. I really love the grippy handle on the brush. It's amazing how much that helps. I wish more companies did that. What do you think of Howl? Do you own any SpaRituals?
