This is a white male mink skin.
The male skins are generally larger than the female skins. They are good quality with weak spots, and may come with or without tails. They are not craft quality or fashion quality but somewhere in between. Male skins tend to have longer hair, denser under fur, and thicker skins than the female ones. When cut open, they are about twice as wide.
Mink are not an endangered species.
The male mink skins, 28-M-WH, are not for export outside of the USA.
