Sorted and weighed then put into batteries, raw skins, formerly called green leathers, are grouped by lots according to their weights and qualities.

The hairs, made up of keratin, are located in the dermis.

THE tanner only transforms the dermis part into leather, the other layers are eliminated. After tanning, irreversible chemical process, leather has a side called flower, the external side, and a flesh side, the internal side.The cattle skin is quickly cut into different parts.
