These nail polishes are fabulous and I love the colour selection especially the nudes and everyday colours. But the darker and more intense colours like the reds and greens stain the crap out of my nails. I have never been interested in using a base coat as it has never extended the wear of any of my polishes which I know could avoid this issue. But even removing these colours get the product everywhere and it really does stain very badly. The quality of the actual product though is very nice and I love the strange shape of the bottle. Something different. The price is also excellent!
