i just bought this stuff from vendors in the middle of the mall halls...you know the ones that pull (more like drag) you in to sample their product and then pretend to take it way below price *just for you of course* well yes...i got pulled in and i loved it...its a kit that has this buffer...with four different sides...one sands it down alittle the other makes it alittle more smooth...then you have your pre buffer and then your ultimate shine buffer side (4 sides in a block looking thing) and i tell you what the look of shiny healthy nails is soo pretty i dont need polish...it helps me to not bite them and helps my nails grow to...the kit also comes with a natural oil to trap your natural shine it lasts for weeks...im telling you i love it....its called Vivo Per Lei Dead Sea Minerals...i love it hehe
