Mas Alla is a binder cover that catches your eye, and won't let go. The vertical stripped tree-bark leather in a rich brown is geometrically custom framed around our new electrifying sunburst copper. The multiple colors in the copper are accentuated and complimented by the rich brown leather. Another example of a branding quality binder cover. Available in all custom sizes, in a wide selection of colors, and with all custom binder cover interior features. Leather is environmentally friendly. Our faux leathers are solvent free to protect the environment. Our copper is recycled copper.
