Source: Jaclyn Kilani / iMore The Mous Limitless 3.0 Walnut Case has been in my possession for a few weeks now, so naturally, I needed the accessories to go with it. The Mous Limitless 3.0 Card Wallet is the perfect companion to this case because it uses the AutoAlign magnetic system to attach effortlessly to any Mous Limitless 3.0 case. Yes, it's similar to the MagSafe system, but in general, the cases and accessories are more affordable than official Apple MagSafe gear. Limitless 3.0 also offers a variety of unique materials like walnut and aramid fiber. My personal favorite case in this line is the walnut material, and the full-grain leather card wallet looks beautiful against the wood panel. The card wallet snaps onto the back of any Mous Limitless 3.0 case and holds two cards securely in place usually. I'll go into more of that later, but first, let's see the pros and cons.
