This file is not as elegant and slender as a glass nail file, but they can not. She's quite a little clunky, but she sits well in the hand with its compact size. The pages are compared to the glass nail file much gross, which is not surprising. However, with sensitivity can pretend very well and she plays here their advantage from the direction of quickly cutting. The change from the large files and the delicate rounding is simple. I can not detect any violations of the nail. For Grobmotoriker this twin is definitely not!
