How to Care for

Your Fanzy Pantz Period Underwear

Rinse After Use

Rinse your Fanzy Pantz period underwear in cold water until clear to remove excess blood and prevent stains.

Machine Wash Gently

Machine wash cold with like colors on a gentle cycle using mild detergent.

Do not use bleach or fabric softener, as this can reduce absorbency.

Air Dry Only

Lay flat or hang to air dry. Avoid tumble drying—heat can damage the absorbent layers and elastic.

Store When Fully Dry

Once fully dry, store your period panties in a clean, dry place or in your Fanzy Pantz pouch.

Are these lace period undies toxin free?

Are these lace period underwear machine washable?
