Neptune is the second polish that I bought from Sinful's Cast Away collection. Just like Zeus, Neptune is another winner from Sinful. (Please excuse how odd my fingers look in these pics. The sun was super bright out yesterday, and it totally washed out my pale skin. The polish is color accurate though!)
Neptune is like the darker, more saturated cousin of several of the blues we've seen in recent collections - it's reminiscent of OPI I Have a Herring Problem and Zoya Skylar, but it is decidedly more blue than either of those. The finish is the same though, that lovely almost micro flake shimmer.
The formula on Neptune is really great - not too thin, not too thick, easy to control. Full coverage in two easy coats. My bottle of Zeus had a wonky brush, but Neptune's brush was just fine.
I honestly couldn't be happier with this polish. I feel like Sinful has really been upping their game lately, and it's so nice to see a $1.99 drugstore brand putting out interesting shades and finishes.
Happy Wednesday, y'all! Thanks for reading! =)
