NOTD: Nails Inc Snowflake

I'm on a gel nail detox - a little different from most other people's January detoxes but my nails have started feeling soft and weak after a few months of constant gel nails. All the buffing and acetone has been a little bit too much and my nails aren't thanking me for it. So instead of a 2 week manicure I'm going to be giving my good old nail varnish the attention it deserves. I've started off with some new ones in my collection. I bought these in the look sale just before Christmas whilst I was wishing for a white Christmas.
These two polishes came in a fab little set with a foil polish too. The snowflake effect polish is really good quality, typical of Nails Inc, needing only one or two coats to have a good covering of glitter and sequins. I think it looks great over the neutral beige Porchester Square colour but will definitely look equally as good over a brighter colour.
An added bonus that it covers up the lumps and bumps that my poor recovering nails currently have.
