This lot has problem on color of natural side of leather was pale not pantone of painting. According to your explanation about natural of leather side, I advised that side can be controlled by selection of darker natural color of leather from beginning before painting is done. Then if selection of natural color can be done at the beginning, it will have no problem. Anyway, the contrast between color on the surface and the natural color of side is signature of this leather. I am afraid that it is difficult to accept this lot when the contrast is different and painting on both sides of leather is not solution in this case as I told you that it was signature of this leather. Please let me know how long does it takes for re-new this lot.
