Collected my Space Gray 1.3 M7 512GB MacBook on Wednesday from the Munich Apple Store, over the moon with it although I haven't had as much time with it as I would've liked yet due to travelling. Accidentally (on purpose) didn't pick up a sleeve for it yet because €80 is simply insane for one. I'm looking for literally the most basic sleeve, plain (black with an apple logo ideally but seems non existent?), no zippers, no magnets, no leather, no fancy design - just protection from scratches when it's in my backpack. Any recommendations?
