11,000

tampons are tossed by the average woman in her lifetime

20 billion

pads + tampons go to North American landfills each year

800

years for non-recyclable fem care products to decompose

My periods are very heavy. Like super heavy tampon every 2 hrs around the clock kind of heavy for 7 days straight. One Proof super heavy pair during the day and one overnight is all I need!
