The Onsen Secret Japanese Nail File Buffet and Shine Kit includes a nail file, grooming oil, a buffing block and 4 buffing replacement pads. The block is used in the order of silver, green, white. Since my wife is still in rehab, I had to test it myself. And what can I say- the result is top- MIRROR smooth, good-looking nails. I had fun doing it myself and it wasn't the last time I did it. My wife knows these polishing blocks from her nail studio and is longingly waiting to finally use them. Thanks to the roller, the care oil is very easy to apply and smells good. The price is not entirely without, but what you get here is also quality again that I did with the article during testing. Thank you for reading my review to the end and I hope that I could help you with your purchase decision. THANKS VERY MUCH
