The best part for me about this nail color is its quality to quickly dry after application. By the time I finished applying first coat on my last nail the first nail had already dried up. So I did a second coat right after the first one and did not have to wait at all in between the coat applications. Since I keep on changing my nail colors on regular basis I do not like to wait much for nail colors to dry. Plus who likes to wait anyway? :p So this is a huge plus for me. Moreover it shines like anything. No top coat is required for extra shine. However you may want to apply it to seal the color. As for the Bourjois claim that it stays up to 7 days I don't think it does because mine has started to chip off after 2 days and I haven't been doing the dishes either. So lasting power is not what it claims to have. Bourjois So Laque! nail colors are priced at Rs. 690 which I would say is steep for a 10 ml nail color. 

So here is my overall assessment of the nail enamel.
