I booked an appointment. All I know is that it stays on for 3 weeks without chipping! This is so perfect for all you lovely brides who want your polish to last all through your honeymoon and some! Oh it's called Cal Gel and not all your nail salons offer this service so be sure to google and ring before making your appointment. I will share my experience with you, after I figure out what all the new rave is about. I'm excited!!
