High school students can use tampons.
Tampon, also known as tampon, is a cotton cylinder, mainly made of cotton, man-made fiber or a mixture of these two materials, with diameters ranging from 1 cm to 1.9 cm. , with a cotton thread (drawstring) attached to the end.
History
Women in ancient Greece often wrapped linen around wood and used it as tampons.
The catheter-type tampon was invented by Dr. Earle Haas of Denver, USA, in 1929. He applied for a patent in 1931 and was launched in the United States in 1936.
Another theory is that tampons are female products designed by a female gynecologist in West Germany in 1950. Because the use of tampons does not affect clothing and exercise, it is loved by many people and is used more by European and American women. Since Asians traditionally dislike suppositories, tampons are rarely used among women in Asian countries.
