This is the second Sinful polish I have used, the colour is a cerise pink, slightly darker than it looks in the photo. It is a glitter polish.
It wasn't as easy to paint with as other polishes but I do like the look. I ended up using four thin coats, although I could probably have got away with three. At first it looked too sheer to give full coverage but by the third coat it was fine.
Edited to add:
The polish lasted really well, in fact after a week it was still perfect which for me is excellent as I tend to be hard on my nails. I only removed it because I wanted to try a different polish colour. It did take 50 minutes to remove, the longest I have ever taken to remove nail polish.
This is the UK range of 'Sinful' and not the US range 'Sinful Colors'.
I will be getting more of the UK 'Sinful' as I love the colours and the way it lasts on the nails. This one was a definite girly pink and I haven't come across this shade of glitter before, very pretty.
My Toma nail polish is very old and so wasn't the easiest to paint with.
I used three coats of the mood changing polish and then two coats of Sinful Cosmic over the top. It did take an age to dry as it was so thick but I am delighted with the result.
It is the first time I have used Sinful polish and I love Cosmic, which is a silver with multi colour glitter. When the nail moves in the light it twinkles. It is sheer enough so that the base colour shows through well.
The Toma mood changing polish changes from purple when cold to blue (although I would say more of a denim than baby blue) when warm, so a great effect with the Cosmic glitter over the top.
If you love glitter polish and haven't tried Sinful Cosmic I highly recommend it. The photo really doesn't do it justice.
