Plastic-based faux vegan leather has a reputation for flaking and cracking. However, next generation plastic-free materials like MIRUM have incredibly impressive technical specifications, and are already being used by prestigious brands with high standards such as BMW. Interestingly, whilst MIRUM is completely natural, it is too hard-wearing to be classified as biodegradable under law. But so is a tree! Just as you don't want your wooden house or furniture to break down whilst you're using it - designer leather accessories should be made to last.
