Leather is a natural product. Distinctive markings and nuances in its texture and color are natural in occurrence and a testament to its authenticity.

Cuttings for approval (CFAs) are recommended for this leather. Expect slight color variation & textures from each hide and dye lot to dye lot. If you opt out of the CFA process, CTL Leather is not responsible for color selections made from swatches.

CFA’s are cuttings to give a general idea of the color reference of the hide & dye lot, but are NOT expected to be an exact colour reference. Dye lot variation is a feature of working with pure anilines, semi anilines and wax pull up leathers and must be understood.

NOTE: Due to color variations on different monitors and color printers, before making exact color and texture matches, we recommend that you request an actual sample to ensure proper color representation as many monitors cannot display colors accurately. CTL Leather is not responsible for color selections made from this website or in lieu of requesting CFAs.
