How false eyelashes distinguish sable from fibrous hair:
1. When ironed with hot water, mink is easy to deform and fiber is not easy to deform.
2. Burn: mink hair has the smell of burning hair, and it is pressed into powder with hands after burning. The fiber has the taste of burning plastic, which looks like a knot in one's heart.
3. The mink hair is made into a single dense row without neat fibers.
4. Look at the wool scales with the microscope. The sable scales are hairy and the fibers are not.
