Shell Cordovan leather is a very rare and difficult material to produce. The tanning process takes about 6 months. The raw material for Shell Cordovan is part of the horse’s hide. Only the horse’s rump is suitable for the production of Shell Cordovan.

For these reasons, Shell Cordovan is a rare and expensive material. I have found about a dozen tanneries that manufacture Shell Cordovan:

1. Horween Leather Company;
2. Shinki Hikaku Co;
3. Maryam Tannery;
4. Conceria Rocado;
5. The Tannery Cloe Srl;
6. Comipel;
7. Lis Royal;
8. Leder Ogawa;
9. Clayton & Son.

I would be grateful if you could add to this list.
