I love this sleeve! I bought it so that my iPad Air 4 and its case would be well protected from scratches, and so far it’s amazing. It did come with a few creases, but I’m going to assume that’s due to travel and/or handling. Either way, I’m going to see whether or not it is durable as the months go by, as I just got it and it feels like it will last long.Edit: while in my possession, the case seemed to hold up well. I migrated to a 12.9 iPad so this case was given to my older sis to use. So farSee full review
