I got this SpaRitual Nail Lacquer in the shade Air Head in my latest edition of Beautyfix (a great way to test products BTW). SpaRitual lacquers are eco-friendly: They are formaldehyde and toluene free. They also have a vegan formulation (but don’t all polishes??? I don’t think animal protein is a regular nail polish ingredient) and use recycled glass for their bottles. They use mica for shimmer instead of fish scales (maybe this is where the vegan note comes from).
The polish is on the sheer side, although it got fairly opaque with two coats. One coat was a bit streaky, but I was happy with it after the second coat. It wore quite well for me, better than many of the polishes that do not have formaldehyde and toluene. I managed to go several days without chipping it, which is good for me.
