This is Australis Nail Paint. I got it from Target in Australia when on holiday in summer. It goes on quite smooth and this colour only needed two coats.
It does last well but I don’t leave nail polish on for long before I change it again so I’m not sure how long it lasts exactly.
I can’t find it for sale in the UK but I would buy more if I could. I’m pretty sure I got it in a bargain bucket so I only got this one colour but it is one I’d get again if I found it.
