This is a #3 grade Kalgan lamb plate. This is an older plate with some discoloration. The color does not match throughout the plate.
The curls of Kalgan lambskins are not as tight as the curls of Pearl lambskins. The hair is 1" and 1.5" pile length and the hair length can vary throughout the same plate.
Do not dry clean the skins as the dry cleaning process will remove the natural oils from the skin.
