In general, these Vegan Leather Bags are commonly made of Polyvinyl chloride (PVC) and Polyurethane (PU). 

 In contrast with Vegan Leather, traditional leather uses animal skin. The most common hide used in manufacturing traditional leather comes from cows.

 It is not surprising that fully dyed leathers are more costly than semi-dyed leathers because it’s more difficult and time-consuming to find better-quality hides that can be dyed. 

 Natural leather usually uses vegetable tanning, which does not use chemicals to dye the leather and instead employs natural colouring methods such as tree bark and tannin. 

 This process takes much longer than other tanning methods, making the leather goods more costly.

 Introducing animals into manufacturing significantly makes it more expensive to manufacture leather, because more resources are needed to harvest them.
