I've had the same leather belt for over eight years. It will probably last another eight. I want to use up my possessions rather than litter the garbage dump with discarded leather so that I can buy an animal friendly replacement. When the time comes for a new belt, I'll opt for the vegan one. That's my personal choice.
Leather is everywhere.
The label on your jeans, the collar on your jacket, the watch strap on your wrist. And don't forget about wool and silk. They're animal products, too. If you chose to remove them from your wardrobe, please pass them on to a thrift store. Home is where the heart is Don't forget about your house.
