Two corrections: 1) Vegan leather isn’t just “fake leather” - it is the skin of a plant or is made of plant derivatives, while fake leather or pleather is made of synthetic materials, like plastic, PVC, and rubber; 2) Having a thicker case doesn’t reduce effectiveness of MagSafe. If the case is MagSafe compatible or otherwise magnetized, the adhesion strength to the wallet is dependent upon the magnet quality and strength within that case.
