Barry M in Pink Multi Glitter and Aqua Glitter - £2.99
I can't rave about Barry M nail varnishes enough, especially the glitter which is opaque in two coats even without a base coat. They are by far the easiest glitter polishes I've ever had the displeasure to remove, the price is extremely reasonable, the brush is decent and the colour range is fantastic.
The pink multi glitter is absolutely beautiful and I will definitely be picking up a few more of these. It's much more of a rose champagne than pink and is the perfect antidote to boring neutral nails (neutral with a little more pay off in fun). The aqua glitter was a little thinner in colour and did need a base coat to get it fully opaque but I could see this working well alone with another coat. I used it as an accent nail with the pink as my outfit was neutral with a pair of statement teal jeans. Matching my nails to my outfit is not usually something I consciously do but these shades just worked so well I thought I just had to.
All in all for £6 for the two these are fantastic and will definitely last me a while. You can usually pick these up on buy two get one free or two for £5 offers which makes them that much more tempting.
