If i didn't remember the price wrongly, its about $20 for normal mani, if use french mani, add another $5. Time huh? Will depends, if its me who can't sit for long and move around, then may take longer. I'll stay there till the nail polish dries up completely(3hrs), else if you need to go ladies huh(that time i did) spoilt one of the nails. You can do 2days before too, but i kiasu, scare it peel off...so one day before for its beauti rather than later i scratch it when working. Eh, they use OPI products also.
Amore was the one who has the free trial cupons. Grace and i signed up their package. $100 for 5 session plus free 2 session(mani only).
