These are great, and work very well.
I love the glass files for natural nails. I experience less breaking, splitting and pealing when I use a good nail file. It leaves a very clean soft edge. I'll update with the quality of nail growth. I am not using this to buff. All three files are the same texture, they are not arranged as file, buff polish. Each file has a textured side and a smooth side. I'm not sure I'd know how these can file and buff and polish, but they do file and shape well.  4 stars.
