I have now realised that the tip wear is caused by Seche Vite which shrinks the nail varnish - you learn something new everyday!! I painted them at night then took photos the following evening and you can see how bad the ends are. I've only noticed it with a few polishes but it's certainly a downside of using Seche Vite.
Also I think Seche Vite are cruelty free, which would be really good. They are owned by the same people as Zoya who are, but I'm not 100% sure yet and will let you know as soon as I find out!
What do you think of this colour? Maybe I will add it to my blog sale...
