Star Nail Super Orange Nail Blocks 126-Count - Professional Nail Buffing & Polishing Kit for Salon & Home Manicures - Perfect for Smoothing, Shining & Prepping Nails Before Polish

These are fantastic I've had them for over a year now just wanted to mention a couple things I noticed people asking in the questions I am not a nail tec but I have and am still learning to do my own nails and these are amazing the grit is not the same on both sides I believe it 80/100 grit which is about the same as a standard nail file so yes these can be used to buff the natural nail for prep before application for that you want to use the 100 side as that is the softer grit also these can be used to shape your natural nails too and if you are using for gel or acrylic application the you can use these to smooth the acrylic or gel or rough them up as they say before applying your gel polish they really are a great investment that will last a long time depending on if you just do your own nails but nail techs I'm sure could go through these pretty fast but the price is amazing I use these all the time and still have many.
