It is an oiled cowhide with a brushed finish to try and add a bit more draw to it. I can occasionally do them in horsehide, either smooth or rough surface.
I do have some kangaroo but I just feel it is too thin for something I want to offer. Mine feels like thick copy paper . While a great, quality leather it just does not impart the same satisfaction of ownership to me as a thicker leather does. I know some have been able to source thicker kangaroo and that would be a material I would be happy to offer at some point.
