I can speak about the example of a menstrual cup, in particular the Bfree Cup, which can be used for upwards of, and sometimes over, 10 years. Compare that to the purchase of traditional products—let's say tampons or pads—that are available from multinationals. At about five or six months or even less—three to four months—you've already paid the price of a Bfree Cup.
