10 days with the No18 Dark Blue/Petrol from Bourjois...I'm not really a 'blue' person. Not a colour I would go for... and what a surprise. Should I use the word 'amazing' again?! Totally suits my olive skin tone. It comes with an angled brush which makes it easy to apply and or retouch. No streaks. I've been 'wearing' my blue nails for a week now and it still looks glossy, no chips even after washing the dishes for 1000 times! Can only recommend. To the bin my essence nail polishes. Bourjois is here to stay!
