We use a bonded leather. 70% of the bonded leather content is leather and 100% of that is from cowhide fibers. The remaining 30% is non-leather substances principally the natural latex as well as tanning oils, vegetable tannins, dyes and leather finishes.
Our Scholars Collection uses bonded leather. There is also the option to add bonded leather to your customized "build-a-DODO" case.
