Are reusable/washable pads a thing?
Yes, they are! They are typically made up of cotton and are changed and used the same as a regular pad. The only difference is that instead of disposing of them after each use in the waste bin, you put them in a clothing hamper for washing.
Yes, they are. There's a washable holder that snaps around the crotch piece of your underwear, and an absorbent pad insert that you can wash, reuse, and even double up on for heavier days.
