Just got this case 4 days ago and i now discovered that it just scratched up my surface along the side. Essentially it is not the case and it's wool/leather itself, but the placement of the pen loop inside (in the side of the case). It only covers the pen on the top, so the bottom is still bare in the case and your surface will go up and down that pen, taking it in and out, rubbing of the matte coating. It probably rubs against the Surface while inside too. Even my pen now has a big line down the side. They did not test that out. This is absolutely depressing i must say. 4 days in, just because of a case/sleeve. (Wrote Marroo already) My Surface is 1.5 month old and looked like new untill now. Just because of a case! Consider yourself warned!
