this review title is: terrible for buffing dip powder and the content is: my experience with these buffer files is only for using them with dip powder nails i always do my own and have been buying buffer blocks from the local beauty supply store for years for cents when i saw these i thought that it would be perfect for me i was wrong these blocks do absolutely nothing i tried to use them all there is very little grit on the blocks at all so it was a task trying to smooth the surface of my nail if you are needing them for something else they may work for you but i would not advice them if you are getting them to do your own nails.there are other information for this review, one is this reviewer did not purchase it and the other is 0 people think this review is helpful.
