I bought this at a swapmeet. The packaging stood out to me and looked like quality polish. I dont know if its because it was out in the sun for who knows how long but the finish is very matte. Litterally looks like I put a thin layer of playdough on my fingernail. I like the color variations but didnt like the finish/look and after a good 10 minutes it still wasnt fully dry and I am able to make indentation in my nail. Good thing this was cheap. I didnt like it at all.

PROS:
Nice color selection
VERY affordable
Readily available
Decent formula

CONS:
Formula can sometimes be runny or not long-lasting
Company does not often come out with new colors

I would re-purchase some colors again, yes. But by no means my favorite brand :(

I bought three shades after hearing such positive reviews. The quality is not as good as brands such as OPI, China Glaze, or Essie. The colour selection isn’t that great either. I would rather shell out the extra bucks and get a better product. I will not repurchase.

i definetly love these nail polishes! they have a great color selection and are very cheap! however with the neon colors you have to apply about three coats but is not a problem for me since every coat dries super fast. And if you do white nail polish as a base first the colors turn out great!!!! im glad i found these great nail polishes with great pigmentation and low price!!! defintely buying them again =)

I love the color selection you can choose from with Sinful Colors, but the formula is so thin and runny, no matter what I do, it ALWAYS pools on my nails. I've tried thin coats, and thick coats, and everything in between, but it STILL pools on the sides of my nails! I need at least 2 coats before I get a nice opaque color, which isn't much to complain about. Just disappointed in how thin and runny the formula is.

I have around four of these polishes, and I must say, I absolutly love them. Usually, I am not the type to wear nailpolish, as it chips and then I flip out about it all day. But these polishes don't chip off too often, and the packaging is study enough so that I can bring it in my bag in case it does chip. The color payoff of these polishes is absolutly amazing! There are subtle sparkles in these that really make my nails gleam and, for lack of better word, flash. The colors reflect the light beautifly. I will definitely purchase more of these.

I bought this for the first time last week. My mani lasted 5 days with no chips! This is great for me!

Sinful colors is a fairly cheap, nice quality nail polish. I find they're a little hit-and-miss, some are exceptional while some are average or a little below average. I have yet to find any truly terrible Sinful polishes. The formulas are mostly smooth and thick, and usually about two coats will do the trick. A few, such as 979 Aquamarine, are super nice and only require one coat for a smooth glossy finish. The staying power is good, but not exceptional. Mine usually last 4-5 days before chipping with a top coat. The price is the main attention grabber of Sinful, being usually about $2 a bottle. It's not the cheapest there is, but for the quality trade off Sinful is very good.

I just bought a ton of these polishes on sale for $0.99. I LOVE the color selection. I'm currently wearing Sinful Colors on my nails WITHOUT top coat (which i usually always wear) and it is pefect and chip-free on the 6th day. My only complaint is that this polish tends to get stringy, but it is manageable. You can reach full opacity with 1-2 coats easily. You can't lose with the great price and great quality.

I love this nail polish! They have so many pretty colors and it lasts for at least a week. For me it's as good as opi if not better. I would definatly recomend this product!
