Numbers are in: an average menstruator uses 5 to 15 thousand pads and tampons in a lifetime. And the vast majority of them will end up in landfills and oceans, and will take 500 years to decompose as they are mainly made of plastic and chemicals. So basically they'll be on your planet much longer than you will. That’s a whole lot of waste that can be avoided by switching to reusable period panties. And they will also make you save money with all the single-use disposable products you won't have to buy each month anymore.
