There are no noticeable stains or fraying. While it provides a secure hold with 3 rows and 7 columns, it was not at all uncomfortable even when eating. I think it should be fine for basic back openings, but for designs with a significantly open back, the shop staff advised that you could unhook the top few rows and fold them inward. I will pack it as carefully as possible, but please understand that this is amateur packing.
