Minerva Full Grain Italian Leather.  Solid Brass Finishings.  Handcrafted.  Made in Detroit.
 
Full Grain: Full grain is the most durable and high-quality leather.  This Minerva leather is from the Badalassi Carlo tannery in Italy. 
Classic: Each dog collar has 2 layers: The Minerva leather outside and a soft veg-tan inner layer for maximum strength and durability.
Brass: Solid brass is extremely hard-wearing in terms of durability and appearance. These pieces can be repeatedly polished and the surface finish remains unchanged, as the whole piece is made of just one metal. In addition to this, solid brass is nickel-free.
