 Something that's environmentally friendly or do you want something that's not? Because believe it or not, using real cow leather that's been tanned will last longer. It's biodegradable. It can be fed like a car from the 50s. You can call it leather food, but you can put that right in the leather and bring the luster back. It'll last for decades, for centuries. But plastic leather does not. The sun hits it. It starts to make it brittle with age. It gets hardened. Just like if you have an old pair of sneakers and you think, wow, this isn't gripping anymore. You have that rubbery grip.
