Here is 2 wiped coats over Butter London Marrow, topped with a coat of OPI Top Coat and Seche Vite. I didn't have any problems with this formula, it was easy to get a good variety of glitters on each nail and they lay flat and smooth. In the photo it looks like they're curling a bit but this is definitely not noticeable in real life.
Here is Butter London Marrow on its own, 2 coats. It's a sophisticated muted shade of purple with a silver shimmer. The formula is smooth as butter (ha ha) and so easy to apply.
I purchased my Butter London polishes from my local chemist which sells them for around $24 each - exxy but so worth it for the colours, formula and sexy square bottle! I've also seen it in sales on BrandsExclusive and Ozsale for around the $13 mark with $10 flat rate shipping.
Thanks for reading!
