I'm not sure if the fur on this muff is Persian or curly lamb. At any rate it has different shades of gray running from light to dark. It also has an unusual shape, different from other muffs that I have seen. The openings for the hands measure 4.75" in length. The handle and lining are made of a brown satin material which is in perfect condition. The muff measures 19.50" across the widest part and 10" from top to bottom. The fur is in excellent condition with no bald spots.
