Our leathers are free of CFC, PCB, PCP, formaldehyde and are dyed with colours that comply with the AZO and other European regulations. The major part of the leathers we use is being pre-tanned with trivalent chromium salts, which are harmless to health, during the first tanning stage. With the re-tanning the chrome content is being extracted out of the leather to a high percentage again and replaced by vegetal tanning agents, like e.g. bark.​Chrome tanning enables the production of especially soft leathers and increases the durability. Only by means of extreme heat or mistakes during the tanning trivalent chromium compounds might turn to the unhealthy chromium VI. Combining the chrome tanning with the vegetal tanning reduces the possibility of chromium VI creation immensely. For guaranteeing our leather to be free from hazardous substances they are regularly controlled by globally recognised laboratories.
