This is one of the mini polishes from the Run The World (Girls) collection, which believe you me, is darn hard to come across in the UK. So I was thrilled to get it even though it was a bit pricey. Mr Posh thinks I'm a total loon! This is a purple one.
This is easy to use and easy to apply. It's fairly weak so needed 3 coats but thankfully it's quick drying. I'd say it was certainly matte - it's described as being "demi matte neon" on the official site. I think it's cool for sure. Lasted well for a matte! Yup good quality and nice colour.
7 out of 10. Good luck for UK people finding it!
