Hi hun.... hmmmm... The none technical answer is... Its a film that you peel off the sheet after a pedi or mani and apply to the nails using heat. It sort of shrink wraps itself to the nail, the heat activates a super strong adhesive. It lasts about 7-10 days (with care) on fingers, and wweeks and weeks and weeks on toes. There are heaps of designs, and lots of metallics, they give you an effect you just can't achieve with polish. If you have a mani cert you can get in touch with sweet squared who supply it, and open an account to order it. Its fab, and very popular. Its my fave thing to wear on toes. The golden cheetah looks AMAZING! Have a look in the groups tab, there is a minx group, and use the search function to look for minx threads, you'll find everything you need to know on there. hth x x
