Thats why I said indirectly, the felt is irrelevant its the grit and then the motion of how those cases are removed that makes some sort of marking unavoidable.
The vaja actually has far less chance of doing anything of the sort - only about 2/3rds of the outside of the iphone is gripped in that way and the case is prized off - the case bends to allow it to pop off - no sliding.

Keep it clean and wipe it out before you put it back on your phone and you will have no issues. I also believe any case that comes in contact with the bezel is going to put small scratches in it over time. As you wipe the screen your pushing dust and lint into the edges of your case, some is going to make it's way underneath the lip of the case and the bezel is going to suffer small scratches.
