Makartt 10pcs Nail Buffer Block Kit - 400/6000 Grit Nail File & Polisher for Natural & Acrylic Nails - Professional Nail Shine Buffer & Smoother for Salon & Home Manicure Care

Is there controversy over whether you should buff your nails? Yes. But when and if you decide to do it, these are GREAT. I had previously been suckered into buying an overpriced set at a mall kiosk, but it frayed and wrinkled and stopped being useful in a matter of days. Here, I got just what I needed, times ten, for a fraction of the price. At first I thought the jump from 400 grit to 6000 grit would be too sudden -- but it worked perfectly. And these absolutely refused to wrinkle or crease -- see the photo I've uploaded with it bent; there's no hint of a wrinkle.What do you use these for?1) You can buff your natural nail to an impressive shine without any polish at all, removing or reducing ridges with the green side first, and finishing with the white side. If you have thin nails, yes, this will thin your nails a tiny bit -- but buff gently, and only when you need to, and you can have great results. This is the controversial part -- some people insist buffing is a good thing, others may start swearing. Men and women alike often do this for a subtle way to shine up their nails and neaten their hands without looking overly primped. I've uploaded new photos of a nail before buffing, after using the coarser green (400 grit) side, and after completing the shine with the very fine white side (6000 grit). I intentionally left my cuticles bone dry and ugly to show that there is absolutely no oil on the nail, and no polish -- it's bone dry and even shinier than it looks in the photo.2) You can gently buff and smooth down a peeling edge on the surface of you nail if you're not brave enough to file off enough length to get rid of it entirely. (I do this when I really want to hold onto what little length I have, but don't want to risk having the peel propagate down my nail.)3) You can use the green side to prep your nails before polish (gel or regular nail polish) if you find that polish peels or chips easily-- it can help some people's polish adhere better because it gives a more grippy surface -- just like you would do before painting a very smooth surface. Just do this only occasionally, and gently, or you could thin your nails more than intended.4) MY FAVORITE -- you can use these buffers to fix a defect in your [fully dried] polish or top coat. See the pictures I've posted -- I was in a hurry and didn't notice the marred finish on my left index finger until the next morning. It took me all of 1 minute to buff it away in 2 steps -- first a quick buff with the green side to smooth the finish, and then a final buff with the white side to restore the shine to original glory and match the other nails. If the defect is too deep -- don't worry -- you can buff down as far as you need, wipe the dust from the nail, and reapply one layer of polish and/or topcoat if needed. You'll get a smoother and longer lasting repair than if you simply tried to polish over the marred nail without buffing -- it's the same idea as refinishing furniture, really. Sanding between layers yields a smoother and longer lasting finish.
