Funny enough those are the actual ones I ordered. Here are my thoughts on the leather I received. Keep in mind I have not bought bison leather before.
Antique whiskey: Looks exactly like the website pictures, leather is flexible and the surface is smooth, not glossy and free of defects The piece is a relatively regular shape . On inspection I did not find any soft spots or holes. Leather measures out at 1.2 - 1.5 mm ( 3- 3.5 oz), a bit thinner than listed on their website. Will be using for some upholstery projects.
Sante Fe: .Firm temper and not as flexible. Surface is smooth and a bit glazed. Again free from defects and regularly shaped. A few wrinkles around the neck area.. Leather is 2.5 - 3.0 mm thick (6-7.5 oz) a bit thicker than listed on their website. This will make some nice cases or briefcases
My thickness measurements are only done on the outer edges. I have not used this material yet some I am unsure how it will work.
Overall I am very happy with my purchase
