Leather under a microscope
Horween **** Strip Macro: 90X: 180X: 270X: If I had to guess, I'd say this is probably horse. I say this based on features that are not exactly visible in the photos, namely the firmness and density of fibers. This is another corrected leather, only clearly with a different treatment...
