I got a SpaRitual polish in a Glossybox, it is super dark red, almost black. I thought it was a good quality polish went on nicely, wasn't streaky and covered in two coats. I would buy more.
I tried this polish and was not impressed. It significantly chipped off after two days on my toes during the summer, when my pedicures usually look great for two weeks. I did not notice any streaking, and initially purchased because it was vegan and free of the usual chemicals. I will stick to OPI.
SpaRitual is Vegan and free of toluene, formaldehyde and DBP. The container is made from recycled materials. A nice selection of colors, some are interesting while others are not ideal for work (too bright). :-) Fun to try. Some of the colors streak w/multiple layers, some don't at all. I love the rubber, easy grip handle. the thing I loved is that I painted my nails one day, the next day, I decided to so some gardening (w/o gloves) and the polish did not chip! That's what made me give a 4 star over some of the streaking issues. I noticed some of the brighter colors seemed to stain the skin than what other nail polishes do. Not sure why.
