Leather is a durable material and is not susceptible to wear and tear like most other materials such as fabric and plastic. Leather is also a very attractive material and adds a touch of class to the product. It is very easy to maintain, and in case of areas that are prone to damage, you can easily cover them with patches, or simply repair them. It is also a very light material, which means that you don’t have to worry about the weight of the bag. There are plenty of reasons for the high costs and resell value of leather bags.
