Menstruation is an important and inevitable part of women's lives from menarche to menopause. Since the 19th century commercial manufacturers have tapped into the lucrative market for the paraphernalia of menstruation. Napkins, both disposable and washable, and belts to support them were amongst the first products commercially produced. Tampons for internal use followed some time later. The American company Johnson & Johnson first manufactured Meds in the 1930s and by 1941 they were available in Australia. Tampons were slow to catch on and were frowned on in many circles, especially for unmarried girls. However, by the 1960s women whose mothers might have forbidden the use of tampons when they were younger, had accepted tampons for all the reasons that manufacturers advertised, including their invisibility, their disposability (just flush down the toilet), and the greater freedom they offered for participation in active sports, especially swimming. This packet of Meds dates from 1970 at the latest and was amongst the personal effects of a woman born around 1920.
