Poor description, poor quality and poor value even at $3.99
The product description is not accurate and the product is unsatisfactory for personal use and natural nails. I find the grit too coarse and all appear to be the same in buffer blocks. There is no buffer to it. Same with the files.  There was no kabuki brush in the package.  I may be able to use on thick toenails and share with friends and family, but otherwise it is a big fat zero.
