Kiss: Nail Artist Paint & Stencil Kit Help!!?

i have this. basically the nailpolish is good (it smells but now once it dries) and how the stencils work is that its kind of like a sticker that you put onto your nail and paint over it then take the sticker off. there are cool designs but idk how many times u can use the same design over before the material just gives away. but its the same value for the money as the single one.
