these are a really easy tip to use, just applay and off you go!!!! if you choose to overlay the tip with white, we do normally do a 3 ball application just to make sure its perfect. it can be done perfectly well in 1 though so its entirely up to you. if you find the nail bed is too short for this tip, dont panic, just trim the smile line with a pair of sharp curved scissors and voila!!!!
if you need any more help, please feel free to ask
