Cotton paper
The banknotes are printed on a cotton-fiber paper with tiny color fibers; that is, small fibers incrusted in the paper and distributed at random. Some of these fibers are visible to the naked eye, while the rest are fluorescent and can only be observed under ultraviolet (also known as "black light"). When the banknotes are observed under black light, they do NOT shine. The imitation banknotes, when observed under black light, DO shine.
