The tanning process used to make this leather uses fewer toxins than traditional leather tanning. This minimizes toxic runoff into the ground and water tables. Throughout the entire process, the leather remains RoHS (Restriction of Hazardous Substances) compliant. No chlorine, no sulfuric acid, and no petroleum/chemical based dyes. This is real leather, without the environmental impact of standard tanning and dyeing processes.
