Has anyone actually tried rubbing some leather protector on the case? curious to see if it helps?
Yes, I put leather protector on both (black & red) of my apple leather cases. I am a leather junkie and I treat all of my leather with some kind of protector. Yes, it helps...
If you do not treat your leather it will bubble from moisture. It happens on all leather, not just Apple leather cases. Anytime water sits on leather it will eventually absorb into the leather causing a bubble. I had a pair of Alden shoes that I wore right out of the box (untreated). It rained later that day and by the time I got home the shoes were bubbled up. From then on I ALWAYS protect my leather pieces as soon as I purchase them.
