I updated the photo's with what's been sold and what left.
Most of them appear to be real leather, if you pick one out I can tell you who makes it and you can visit their website and check. Most of them are made by they "Stephi" Corporation..

The EastSide collection the one's with the rhinestones are "Faux Leather".
A few of them are made by "Leather Brothers" and some are made by "Chrome Bones".
