I have the glas.tr nano slim and I have always used it with no case and it has always fine. You have to be careful because it will chip/crack like mine has because I dropped my phone face down on tile.

You can use a case but overtime it does start to develop small cracks on the side. I had to get mine replaced 3 times, the 4th time I bought a new tempered glass shield from MIME, 2 months no cracks or scratches with no case.
