I think its safe to say that I am a nail polish addict, and it is not getting any better. So, that being said, I have had my eyes on the neon shades from colorbar and have lusting them for a long time now.
There are a lot of colours in the range, and these are the ones that I own. What I most like about them is the colour payoff. its exactly what its like in the bottle. What I mean is that some nail polishes look fabulous in the bottle, and then when I apply them, they turn out to be sheer, even after 3 coats!
The first coat is a bit sheer, but once you apply the second coat the true colour shows up. They are quite competitively priced at 175/- which is not bad when compared to other brands, and the size of the bottle.
I wouldn't say these are long lasting though, they stay for around 2-3 days max, and starts chipping at the edges unless you have a good top coat on. I like to use the Sally hansen one.
If you want your neon colours to look matte, add a bit of cornflour to the polish before applying them and viola your nail polish will dry matte. Alternatively, you could add corn flour to a clear polish, and use that as a top coat, this way you can turn any of your polishes matte!..
Do let me know if you try this out!
