Genuine leather doesn't just mean that the product is made of real leather, but it also means it is the lowest quality of all products made out of real leather.
Genuine leather generally doesn't last as long or look as nice as higher-quality leather.
You'll typically find it in belts from mall stores, shoes from lower-priced department stores, and bags or other goods in the lower-leather price range.
Goods marked as genuine leather will be several layers of low quality leather bonded together with glue and then painted to look like a better-quality leather.
It's what is left over when the other, higher grades are stripped away.
This grade of leather is acceptable if you're just buying something cheaply and don't care too much about its quality.
It won't last very long, so it probably shouldn't be something you use every day.
Another use for genuine leather is suede, which has been textured to have a napped finish.
Suede is often confused with nubuck, which is a grain leather that is textured to have a similar nap finish.
The difference is that nubuck is much stronger and more durable than suede, though suede’s softness and pliability make it useful for certain applications.
