Jen Gunter Instagram – I took a little trip down menstrual memory lane to compare the most absorbent menstrual pad from the late 1970s to technology of today. I had very heavy periods, so I used the most absorbent pad I could find, Kotex New Freedom. I was able to buy a small box on Etsy! I then bought what looked like the most absorbent @kotex_brand of today. Look at the difference in size!! This is not an ad. I used Kotex back in the day, so I wanted to compare brand-to-brand.
